What Is Windsurf?

Windsurf is an AI-native code editor built on a fork of VS Code, with an autonomous agent called Cascade at its center. From plain-English prompts, it reads your codebase, writes and edits code across multiple files, and runs terminal commands while keeping context as you work.

It is built for beginners, vibe builders, and professional developers who want AI woven into the editor rather than bolted on. I have used Windsurf on real projects over several months, and the cleanest way to describe it is an editor that drives itself when you let it. You describe what you want, and Cascade plans the change, touches the files it needs, runs the commands to verify, and shows you a diff to approve. It is closer to pair programming with an agent than to autocomplete.

Windsurf began as Codeium, an AI autocomplete tool, before the company rebranded the product to Windsurf in late 2024 and shifted the focus to the agentic editor. According to Fortune, OpenAI agreed to acquire the startup for about $3 billion in 2025, which tells you how seriously the market took it. The product is now owned by Cognition, the maker of the Devin coding agent.

The defining idea is "flow." Windsurf tries to keep you in a single loop where you think, prompt, review, and ship without context-switching to a separate chat window or a different tool. The Cascade agent maintains awareness of your project so that each instruction builds on the last, which is the behavior that made the editor popular with developers in the first place.

In late 2025 Cognition began folding Windsurf into a broader product called Devin Desktop, described in the official docs as a next-generation AI IDE that manages local and cloud agents from one surface. The Windsurf editor and brand still exist, the pricing page still sells Windsurf plans, and the changelog still lives at windsurf.com, but the product is actively merging with Cognition's Devin lineup. This guide covers Windsurf as it stands today and flags where it is heading.

The Windsurf Saga: From Codeium to Cognition

Windsurf went from a $3 billion OpenAI acquisition to a broken deal to a split sale across Google and Cognition, all inside a few days in July 2025. It is one of the strangest sequences in recent software history, and understanding it explains why the product looks the way it does now. Here is the verified timeline.

The story starts with Codeium, an AI coding company founded by Varun Mohan and Douglas Chen. The team built a popular autocomplete tool, then pivoted to the agentic editor and renamed the product Windsurf. The editor's "flow" pitch and the Cascade agent drove fast adoption among developers.

According to CNBC, OpenAI entered talks in April 2025 to buy Windsurf for about $3 billion, which would have been OpenAI's largest acquisition to date. Bloomberg reported that OpenAI reached an agreement to buy the startup for that figure in May 2025. For a couple of months, Windsurf looked set to become an OpenAI product.

The deal then collapsed. According to Fortune, the exclusivity period on the $3 billion agreement expired in July 2025, and the acquisition fell apart. Reporting attributed the breakdown to OpenAI's partnership with Microsoft, which gave Microsoft rights to IP OpenAI acquired, terms OpenAI could not guarantee for Windsurf and Microsoft would not renegotiate.

What followed was a 72-hour scramble. On July 11, 2025, Google struck a licensing deal that brought Windsurf's CEO Varun Mohan, co-founder Douglas Chen, and roughly 40 senior researchers into Google DeepMind, while Windsurf stayed an independent company. Three days later, on July 14, Cognition signed a definitive agreement to acquire Windsurf's remaining assets.

According to Cognition's own announcement, that acquisition included Windsurf's IP, product, trademark, brand, an $82 million ARR business with enterprise revenue doubling quarter over quarter, 350+ enterprise customers, and hundreds of thousands of daily active users. Crucially, Cognition noted the Windsurf IDE would now ship with full access to the latest Claude models, resolving an earlier period when Anthropic had restricted Windsurf's Claude access. The product you use today is the result of that final deal.

Who Is Windsurf For?

Windsurf works for three groups: complete beginners learning to build with AI, vibe builders shipping projects without deep coding experience, and professional developers who want an agent inside their editor. Here is how each group benefits.

For Complete Beginners

Beginners get a real code editor that does the hard parts for them. Cascade can scaffold a whole project, explain what each file does, and fix errors when you paste them in, so you learn by watching working code appear rather than starting from a blank file.

The free tier lets you try this without paying. You can write your first app, ask the agent to add features in plain English, and see the changes applied as diffs you approve, which teaches you how software fits together while the agent handles the syntax.

If you have ever opened a code editor and felt lost, Windsurf lowers that wall. You describe the outcome you want, and the agent turns it into files, while you stay in one window and read along.

For Vibe Builders

Vibe builders get a fast path from idea to a running app without writing most of the code yourself. Cascade handles multi-file changes, runs the commands to install dependencies and start the app, and keeps the project coherent as you iterate.

This is the group Windsurf serves well. You can build a dashboard, a landing page, or an internal tool by describing it, then refine it through conversation, with the agent doing the plumbing across the front end and back end. The flow-focused design means you spend your time deciding what to build, not wrestling with tooling.

Because Windsurf is a full editor rather than a web sandbox, your project lives on your machine in real files you own. That matters when you outgrow the prototype and want to deploy it or hand it to a developer.

For Professional Developers

Developers get an agent that understands a large codebase and acts across it, inside a familiar VS Code-based editor. Cascade indexes your project for context, so its edits respect your existing patterns rather than treating every prompt as a fresh start.

The honest framing is that Windsurf is an accelerator for the work you already know how to do. It is strong at multi-file refactors, writing tests, fixing failing builds, and generating boilerplate, and it shows every change as a reviewable diff so you stay in control of what lands.

Full access to frontier Claude models, plus Cognition's own SWE models, means you can pick the engine that suits the task. For complex agentic work you reach for a strong model, and for quick edits a faster one keeps the loop tight, all without leaving the editor.

Every Feature That Matters in 2026

Windsurf's value comes from a handful of features built around the Cascade agent and the flow idea. These are the ones worth understanding before you commit.

Cascade: The Agentic Core

Cascade is Windsurf's flagship agent, and it is what separates the editor from plain autocomplete. It reads your codebase, plans a change, edits the files it needs, runs terminal commands, and reports back, all from a single instruction.

The practical effect is that you delegate whole tasks rather than single lines. You can ask Cascade to add a feature, fix a failing test, or refactor a module, and it works across the project instead of inside one file at a time.

Every action is reviewable. Cascade shows diffs for code changes and asks before running commands that matter, so you keep a human checkpoint on autonomous work, which is the right default for anything beyond a throwaway script.

Deep Codebase Context Awareness

Windsurf indexes your entire project so the agent understands how your files relate. According to Windsurf's documentation, this context awareness lets the editor instantly understand your codebase, which is why its suggestions tend to match your existing conventions.

This matters more than it sounds. An AI edit that ignores the rest of your code creates bugs and inconsistency, while one that respects your patterns reads like something you would have written. Context awareness is the difference between a helpful agent and a noisy one.

The index updates as you work, so the agent stays current with your latest changes. You are not re-explaining your architecture every session, because the editor already holds it.

Tab Autocompletion and Inline Edits

Windsurf keeps the fast, low-friction tools alongside the agent. Tab completion predicts your next edit, and inline edits let you select code and change it with a prompt, both of which stay useful even when you are not running a full agent task.

These are the moves you make hundreds of times a day. The pricing page lists unlimited inline edits and unlimited Tab completions even on the free plan, so the everyday flow is not gated behind a paywall.

The combination is what makes the editor feel quick. Tab and inline edits handle small changes instantly, while Cascade handles the larger, multi-step work, and you move between them without thinking about it.

Full Access to Frontier Models

Windsurf gives you a choice of underlying AI models rather than locking you to one. According to Cognition's acquisition note, the Windsurf IDE ships with full access to the latest Claude models, and the pricing page lists access to OpenAI, Claude, and Gemini frontier models on paid plans.

Model choice matters because different engines suit different jobs. A strong reasoning model handles a tricky refactor better, while a faster model keeps simple edits snappy, and Windsurf lets you switch between them inside the same editor.

The platform also includes Cognition's own SWE models, with SWE 1.6 available as the latest in-house option. Free use of SWE models on paid plans means you can lean on a capable engine without burning your premium model quota on routine work.

MCP, Memories, and Workflows

Windsurf supports the Model Context Protocol (MCP), persistent memories, and saved workflows, which turn the editor into a customizable agent platform. According to Windsurf's docs, MCP servers extend the agent's capabilities, memories and rules customize its behavior, and workflows automate repetitive trajectories.

MCP is the standout here. It lets the agent connect to external tools and data sources through a standard interface, so Cascade can reach beyond your code into the services your project depends on.

Memories and workflows make the editor yours over time. The agent remembers your preferences and project rules, and you can save a repeated sequence of steps as a workflow you trigger on demand, which compounds into real time savings.

One-Click App Deploys and Terminal

Windsurf includes an upgraded terminal and one-click app deploys, so the loop from writing code to seeing it live stays inside the editor. According to the docs, App Deploys let you deploy applications in one click, and the Terminal is an upgraded experience compared to a stock editor terminal.

This closes the gap that usually breaks flow. Instead of switching to a separate hosting dashboard, you ask the agent to deploy, and the app goes live, which keeps a beginner or vibe builder from stalling at the last step.

For developers the integrated terminal means the agent can run, test, and debug your code in the same place you read it. Cascade uses that terminal to verify its own work, which is a large part of why its changes tend to actually run.

What I Like and What Falls Short

Windsurf is the editor I reach for when I want an agent-first flow with clean defaults, but it has real trade-offs worth naming. Here is where it shines and where it does not.

What Works Well

• The Cascade agent handles multi-file changes, runs commands, and shows reviewable diffs, so you delegate whole tasks rather than single lines (Windsurf docs).
• Deep codebase context awareness means edits respect your existing patterns instead of fighting them (Windsurf docs).
• Unlimited Tab completions and inline edits even on the free plan keep the everyday flow fast without a paywall (Windsurf pricing page).
• Full access to frontier Claude, OpenAI, and Gemini models, plus Cognition's SWE models, lets you match the engine to the task (Cognition, 2025).
• A genuinely capable free tier lets you build a real app before paying anything (Windsurf pricing page).
• MCP, memories, and workflows turn the editor into a customizable agent platform rather than a fixed tool (Windsurf docs).

Where It Falls Short

• The product is mid-transition into Devin Desktop, so branding, docs, and some features are shifting under you, which can be confusing (Windsurf docs, 2025).
• Usage quotas on paid plans can feel tight for heavy agent use, and credit-style limits have drawn community complaints.
• The ecosystem is smaller than Cursor's, so you find fewer community guides, extensions, and shared configs.
• Pricing changes have happened more than once during the ownership turbulence, so the plan you sign up for may evolve.
• For pure terminal-native autonomy, a dedicated CLI agent like Claude Code can run longer unattended jobs more comfortably.

Windsurf vs Cursor: Which Should You Use?

Choose Windsurf when you want a clean, agent-first editor with full Claude access and a strong flow design. Choose Cursor when you want the larger ecosystem, the most mature feature set, and the biggest community.

The two are the leading AI-native code editors, and both are VS Code forks with a powerful agent. The real difference is maturity and momentum. Cursor, rated 9.5 in our directory, has the larger user base, a deeper feature set, and far more community content, while Windsurf, rated 9 in our directory, leans on its flow-focused design and the Cascade agent's clean multi-file workflow.

For most developers the decision comes down to ecosystem versus design. If you value the widest pool of guides, configs, and battle-tested features, Cursor is the safer default. If you prefer Windsurf's tighter agent loop and want full Claude model access in a less cluttered editor, Windsurf is the sharper pick. I keep both installed and reach for Windsurf when I want the agent to drive and Cursor when I want maximum control and tooling.

Windsurf vs Claude Code: The Honest Comparison

Choose Windsurf when you want a visual editor with diffs, a project explorer, and an agent you watch work. Choose Claude Code when you want a terminal-native agent that runs long, autonomous coding jobs from the command line.

These tools solve the same problem from opposite directions. Windsurf is a graphical IDE where the agent works alongside you and every change appears as a reviewable diff in a familiar editor. Claude Code, rated 9.6 in our directory and made by Anthropic, is a CLI agent that lives in your terminal and is built to plan, write, test, and commit code across a whole project with minimal hand-holding.

The decision usually comes down to how visual and how autonomous you want the experience. If you like seeing your files, clicking through a project, and approving changes in an editor, Windsurf fits. If you are comfortable in a terminal and want to hand off larger tasks to run unattended, Claude Code fits. Many developers use both, reaching for Windsurf for interactive editing and Claude Code for heavier background work.

Windsurf vs Plain VS Code: What You Actually Gain

Choose Windsurf when you want an AI agent built into the editor from the ground up. Stick with plain VS Code plus an extension when you want maximum stability and a setup you already trust.

Windsurf is a fork of VS Code, so the core editing experience feels familiar, with the same keyboard shortcuts, settings, and a compatible extension ecosystem. What you gain is the deep integration: Cascade, context awareness, and the flow design are built into the application rather than added as an extension that talks to a separate process.

The trade-off is integration versus neutrality. Plain VS Code with an AI extension lets you keep Microsoft's editor and swap AI tools freely, but the experience is less unified than an editor designed around its agent. For AI-first work I prefer Windsurf's native integration. For a locked-down corporate setup or a workflow built on specific VS Code extensions, the stock editor with an add-on can be the calmer choice.

Pricing and Plans: What Each Tier Actually Gets You

Windsurf uses a tiered subscription model with a free starting plan, verified against the live pricing page in 2026. The plans now share branding with Cognition's Devin lineup, but the tiers and prices below are what the pricing page sells today.

Which plan should you choose? If you are learning or testing the editor, start on the free plan, where unlimited Tab and inline edits already cover a lot of everyday work. If you build regularly and want full model access and cloud agents, Pro at $20 a month is the natural home for an individual. If your agent usage is heavy or you run many concurrent sessions, Max at $200 a month removes the quota ceiling that frustrates power users.

The detail to watch is quota rather than price. The free and lower tiers cap how much agent work you can do, and during the ownership turbulence the usage limits have changed more than once. Estimate how much heavy agent work you do before committing, because the gap between Pro and Max is entirely about headroom.

Windsurf has no affiliate program that I use, so I have no financial incentive to recommend any particular tier. I recommend Pro for most individual builders because it unlocks full model access at a price that stays reasonable, and I only move to Max when a project's agent usage genuinely outgrows it.

How I Built a Dashboard with Windsurf

I built a small analytics dashboard in Windsurf to test whether the flow pitch held up on a real project, and the first working version took an afternoon. I wanted to see whether Cascade could carry a multi-file build rather than only a single-file demo.

The process stayed conversational from the start. I described the dashboard I wanted, with charts, a data table, and a filter bar, and Cascade scaffolded the project, created the components, wired up the state, and ran the commands to install dependencies and start the dev server. I approved each diff as it appeared rather than letting it run blind.

Context awareness was the part that saved the most time. When I asked for a new chart, the agent matched the styling and structure of the components it had already written, so the codebase stayed consistent instead of drifting with each addition. That is the behavior Windsurf's documentation describes as instantly understanding your codebase, and on this build it held up.

The model choice mattered more than I expected. I used a strong Claude model for the trickier state logic and a faster model for routine edits, switching inside the same editor, which kept the loop tight without sending every small change to a heavy engine. Full frontier model access, which Cognition confirmed shipped with the IDE after the acquisition, is what made that flexibility possible.

The honest friction was quota. Heavy agent use on a lower tier hit the usage ceiling faster than I liked, so I learned to batch related changes into clearer prompts rather than firing dozens of tiny ones. That single habit stretched my usage and, as a bonus, produced cleaner diffs.

The verdict from the build is that Windsurf delivered a working, coherent dashboard faster than coding it by hand, with the trade-off that I stayed mindful of quota and reviewed every change. For the speed it gave me, that trade was easily worth it.

Getting Started: Your First 30 Minutes

Download Windsurf, sign in, open or create a project, and give Cascade your first task. Here is the exact path.

1. Download the editor from windsurf.com. Pick the build for Mac, Windows, or Linux and install it like any desktop app. It opens to a familiar VS Code-style layout, so if you have used VS Code you already know your way around.

2. Sign in and pick a plan. Create an account and start on the free tier, which includes unlimited Tab completions and inline edits plus a light agent quota. You can upgrade to Pro later without reinstalling anything.

3. Open a project or start a new one. Point Windsurf at an existing folder, or ask Cascade to scaffold a fresh project from a description. The editor indexes your code so the agent understands the structure before you give it work.

4. Give Cascade a real task. Open the Cascade panel and describe what you want in plain English, for example "add a contact form with validation." The agent plans the change, edits the files, and shows you diffs to approve before anything lands.

5. Use Tab and inline edits for small changes. For quick tweaks, accept Tab suggestions as you type, or select code and prompt an inline edit. These stay fast and unlimited even on the free plan, so use them for the dozens of small edits in a session.

6. Let it run and verify. Allow Cascade to run the terminal commands to install dependencies and start your app, approving each step. Watching the agent verify its own work in the integrated terminal is the core Windsurf loop you will use from here on.

10 Things I Wish I Knew Before Starting

Cascade is the whole point, so use it for real tasks. The agent is strongest on multi-file work like adding a feature or fixing a build, not single-line edits. Treat it like a junior developer you delegate to, and review every diff it produces.

Tab and inline edits are unlimited on free. According to the pricing page, even the free plan includes unlimited Tab completions and inline edits, so you can do a lot of everyday coding before you ever hit a paywall.

Model choice changes the experience. Paid plans give you Claude, OpenAI, and Gemini frontier models. Use a strong model for hard logic and a faster one for routine edits, and switch inside the editor as the task changes.

Quota, not price, is the real constraint. The lower tiers cap how much agent work you can do, and those limits have changed during the ownership transition. If you run heavy agent jobs, expect to feel the ceiling before you feel the price.

It is a VS Code fork, so your habits transfer. Your shortcuts, settings, and most extensions carry over, which means the learning curve is about the agent, not the editor. That makes the switch from VS Code genuinely low-friction.

Context awareness needs the project open. The agent indexes your codebase, so work inside a real project folder rather than scattered files. The more complete the project, the better its edits match your patterns.

MCP unlocks the agent's reach. Connecting MCP servers lets Cascade use external tools and data through a standard interface. If your project depends on outside services, MCP is how you let the agent touch them safely.

Memories and workflows compound. The agent remembers your rules and preferences, and you can save repeated sequences as workflows. Setting these up early pays off across every later session.

The product is merging into Devin Desktop. Cognition is folding Windsurf into a broader IDE called Devin Desktop, so expect branding and some features to shift. The Windsurf editor and pricing still exist, but the roadmap is moving.

Review everything the agent does. Autonomous edits are powerful and occasionally wrong. The diff-and-approve flow exists for a reason, so read the changes before you accept them, especially on anything that touches data or auth.

Common Problems and How to Fix Them

Most Windsurf friction comes from quota limits and from expecting the agent to be right without review. Here are the issues people hit most, drawn from community discussions and reviews.

I hit my usage quota faster than expected

Batch related changes into fewer, clearer prompts, because each agent task consumes quota regardless of how small it is. If you genuinely need more headroom, the free and Pro tiers cap heavy agent use, so moving to Max removes the ceiling for power users who run the agent constantly.

Cascade made a change that broke my build

Read the diff before approving, and use the integrated terminal to let the agent run and verify its own work. If a change already broke something, ask Cascade to fix the specific error and paste the failing output, because the agent fixes errors far better when it can see the exact message.

My extensions or settings did not carry over

Re-import your VS Code profile, since Windsurf is a fork and supports most VS Code extensions and settings. If a specific extension fails, check whether it relies on a Microsoft-only marketplace feature, because a small number of extensions are tied to the official VS Code build.

The agent ignores my project conventions

Make sure the whole project is open so the editor can index it, and add a memory or rules file describing your conventions. Context awareness depends on the agent seeing your codebase, so working in a complete project folder is what makes its edits match your style.

I am confused about Windsurf versus Devin Desktop

Treat Windsurf as the editor you download today and Devin Desktop as where Cognition is taking it. The Windsurf brand, pricing, and changelog still operate, but the docs increasingly describe Devin Desktop, so expect the two to converge over the coming releases.

I lost access to a Claude model I was using

Check your plan's model availability, because frontier model access is tied to paid tiers. After the Cognition acquisition the IDE shipped with full Claude access, so if a model is missing it is usually a plan or quota limit rather than a removal.

Costs are higher than I expected on a team

Open the admin dashboard on the Teams plan to see usage by member, since heavy agent users drive most of the cost. The Teams plan bills $80 a month plus $40 per developer seat, so audit who actually needs a full seat before adding everyone.

Frequently Asked Questions

These are the questions people ask most about Windsurf, drawn from Google's People Also Ask results and community threads. Each answer stands on its own.

What is Windsurf AI?

Windsurf is an AI-native code editor built on a VS Code fork, with an autonomous agent called Cascade that reads your codebase, writes code, runs commands, and edits multiple files from plain-English prompts. It started as Codeium and is now owned by Cognition, the company behind the Devin coding agent.

Is Windsurf AI free?

Windsurf has a genuinely free plan, though heavy use needs a paid tier. According to the pricing page, the free plan includes a light agent quota, unlimited Tab completions, and unlimited inline edits. Paid plans start at $20 a month for Pro, which adds full frontier model access and higher quotas for serious work.

How much does Windsurf cost per month?

Windsurf costs nothing on the free plan, $20 a month for Pro, and $200 a month for Max, per the pricing page. The Teams plan is $80 a month plus $40 per developer seat, and Enterprise is custom-priced. Each step up mainly buys higher usage quotas and broader model availability rather than entirely new features.

Is Windsurf AI Chinese?

No, Windsurf is not a Chinese company. It was founded in the United States as Codeium by Varun Mohan and Douglas Chen, later renamed Windsurf, and is now owned by Cognition, a US company that also makes the Devin agent. The confusion usually comes from mixing it up with unrelated tools.

What happened with Windsurf and OpenAI?

OpenAI agreed to acquire Windsurf for about $3 billion in May 2025, but the deal collapsed in July when the exclusivity period expired. According to Fortune, OpenAI's IP-sharing terms with Microsoft were the sticking point. Google then hired Windsurf's CEO and key staff, and Cognition acquired the remaining assets.

Who owns Windsurf now?

Cognition owns Windsurf. According to Cognition's announcement, it acquired Windsurf's IP, product, trademark, brand, and most of its team in July 2025, after the OpenAI deal fell through and Google hired the CEO. Cognition also makes Devin, and is merging Windsurf into a broader product called Devin Desktop.

Is Windsurf a fork of VS Code?

Yes, Windsurf is built on a fork of Visual Studio Code. The editor's layout, keyboard shortcuts, and most extensions feel familiar to existing users, while Windsurf adds its own AI agent and context awareness on top. Choose Windsurf when you want that native agent, and stay on plain VS Code when you need maximum stability.

Is Windsurf better than Cursor?

It depends on your priorities. Choose Windsurf when you want a clean, agent-first editor with full Claude access and a tight flow loop. Choose Cursor, rated 9.5 in our directory, when you want the largest ecosystem, the most mature features, and the biggest community. Cursor leads on momentum, Windsurf on focused design.

Windsurf vs Claude Code: which should I use?

Choose Windsurf when you want a visual editor where you watch the agent work and approve diffs. Choose Claude Code, rated 9.6 in our directory, when you want a terminal-native agent that runs long autonomous jobs from the command line. Windsurf is the interactive IDE, Claude Code is the headless CLI agent.

What is Cascade in Windsurf?

Cascade is Windsurf's flagship AI agent. It reads your entire codebase, plans a change, edits the files it needs, runs terminal commands, and shows you reviewable diffs, all from a single instruction. Cascade is what turns Windsurf from an autocomplete tool into an agent that can complete whole tasks for you.

Does Windsurf support multiple AI models?

Yes, Windsurf gives you a choice of models on paid plans. According to Cognition, the IDE ships with full access to the latest Claude models, and the pricing page lists OpenAI and Gemini frontier models plus Cognition's own SWE models. You switch models inside the editor to match the engine to each task.

Is Windsurf good for beginners?

Yes, Windsurf works well for beginners. The Cascade agent can scaffold a whole project, explain the code, and fix errors you paste in, so you learn by reading working code rather than starting from blank files. The free tier and the familiar editor layout make it an approachable first AI coding tool.

What is SWE 1.6 in Windsurf?

SWE 1.6 is Cognition's in-house software engineering model, available inside Windsurf and Devin. It is offered free of premium quota on paid plans, so you can run capable agent work without spending your frontier-model allowance. It sits alongside the Claude, OpenAI, and Gemini models you can also choose in the editor.

Can Windsurf run terminal commands?

Yes, Windsurf includes an upgraded integrated terminal, and the Cascade agent uses it to install dependencies, start your app, and verify its own changes. You approve commands that matter before they run, which keeps a human checkpoint on the agent while still letting it test the code it writes.

What is the difference between Windsurf and Devin Desktop?

Windsurf is the editor you download today, and Devin Desktop is the broader product Cognition is building from it. The Windsurf brand, pricing, and changelog still operate, but the docs increasingly describe Devin Desktop as a next-generation IDE that manages local and cloud agents. Expect the two to converge over coming releases.

Does Windsurf work offline?

Windsurf needs an internet connection for its AI features, because the models that power Cascade, Tab completion, and inline edits run in the cloud. The editor itself opens offline like any VS Code build, so you can read and edit files, but the agent and completions require a connection to work.

The Verdict: Should You Use Windsurf in 2026?

Windsurf is one of the best AI-native code editors available, and the right default for anyone who wants an agent-first flow with full Claude access. How strongly that applies depends on who you are.

If You're a Complete Beginner

Use Windsurf. It is an approachable way to start building, because Cascade scaffolds projects, explains the code, and fixes errors while you watch working software appear. Start on the free plan, learn how the agent's diff-and-approve loop works, and upgrade to Pro only when you outgrow the free quota.

If You're a Vibe Builder

Use Windsurf. The flow design and the Cascade agent let you go from idea to a running app by describing it, with the agent handling the multi-file plumbing. Build on Pro for full model access, batch your prompts to conserve quota, and keep your project in real files you own and can deploy.

If You're a Professional Developer

Use Windsurf as a strong agent inside a familiar editor, while keeping an eye on the Devin Desktop transition. It excels at multi-file refactors, tests, and build fixes, with reviewable diffs that keep you in control. If you also need terminal-native autonomy for long unattended jobs, pair it with Claude Code rather than choosing one.

My Honest Recommendation

Windsurf is the editor I reach for when I want an agent to drive inside a clean, VS Code-based workflow, and I recommend it with two honest caveats: watch your usage quota, and expect the product to keep shifting as Cognition merges it into Devin Desktop. It survived one of the wildest acquisition sagas in software and came out with full frontier model access intact, which says something about the product's strength. Start on the free plan, build something real, and move to Pro when the agent becomes part of how you work.
