Browserbase

Browserbase is a serverless browser infrastructure platform from the Browserbase team that runs production-grade headless Chromium sessions for AI agents and automation workflows. Where most teams burn weeks fighting headless browser maintenance, anti-bot detection, and CAPTCHA loops, Browserbase ships a managed cloud fleet with session replays, stealth mode, and a clean REST API.

What Browserbase does:

• •Managed headless browser sessions run scalable, isolated Chromium instances in the cloud with no infrastructure to maintain, no Docker images to build, and no proxy rotation to manage.
• •Session recordings and replays every browser session is captured as synchronised video plus DOM and network logs, so debugging an agent failure takes minutes instead of guessing from text logs.
• •Stealth mode and identity built-in fingerprinting, residential proxies, and CAPTCHA handling let agents operate on sites that block standard headless browsers, with significantly higher success rates than vanilla Playwright.
• •Fetch API for lightweight scraping a separate Fetch endpoint retrieves rendered page content without spinning up a full browser, optimised for low-latency, high-volume static scraping jobs.
• •Stagehand caching intelligent caching of repeated browser actions reduces latency and cost for agents that revisit the same sites repeatedly.
• •Native Playwright and Puppeteer SDKs existing Playwright and Puppeteer scripts work with a one-line connection-string change, so migrating from local headless browsers is painless.
• •Browser extension and authenticated sessions attach Chrome extensions and persist authenticated cookies across sessions for workflows that need to log into specific accounts repeatedly.
• •MCP support a native Model Context Protocol server exposes browser actions as tools to MCP-compliant agents, so any MCP client can drive a remote Chromium session without bespoke glue code.

Pricing:

• •Free $0/month: 3 concurrent browsers, 1 browser hour, and 1,000 Search/Fetch calls. Enough to evaluate the platform on a real workflow.
• •Developer $50/month: 25 concurrent browsers, 100 browser hours, advanced stealth and identity features, and basic session retention.
• •Startup $250/month: 100 concurrent browsers, 500 browser hours, 30-day session retention, and priority queue access.
• •Enterprise custom pricing: 250+ concurrent browsers, usage-based scaling, dedicated support, SOC 2 reports, and custom data retention.

Limitations:

• •You bring your own AI logic Browserbase is the headless browser infrastructure, not an end-to-end automation tool. You wire it to an LLM, write the agent loop, and handle decision-making yourself. Expect real engineering before the first workflow runs.
• •Bot detection failures still happen on hard targets LinkedIn, Google, and major banking portals actively block headless browsers, so roughly 6 in 10 attempts on those sites can fail even with stealth mode. Browserbase smooths the easy 80%, not the adversarial 20%.
• •Minimum one-minute billing per session even if a session completes in 10 seconds, you pay for a full minute. Workflows that open many short sessions multiply cost faster than expected, so batching is essential.
• •Multiple billing lines that add up the Developer plan starts at $50/month, but proxy bandwidth, Search API calls, and Fetch API page calls are billed separately. Real monthly invoices are noticeably higher than the headline plan price.
• •Selectors break on layout changes Browserbase does not ship AI-native element selection. Automations rely on XPath or CSS selectors that break when target sites redesign, requiring ongoing selector maintenance.
