Browserbase

Browserbase provides a managed, serverless environment that handles the heavy lifting of browser maintenance and anti-bot detection. It bridges the gap between AI agents and the real web by offering a stable, programmable interface for complex navigation tasks.

What Browserbase does:

• •Headless browser sessions run scalable, isolated browser instances in the cloud without managing your own infrastructure.
• •Session recordings debug agent behavior by reviewing synchronized video and network logs for every interaction.
• •Stealth mode bypass common anti-bot protections and CAPTCHAs using built-in identity and fingerprinting features.
• •Fetch API retrieve web content efficiently without the overhead of a full browser session for simple data extraction.
• •Stagehand caching improve agent performance and reduce latency by leveraging intelligent caching for repetitive web tasks.
• •Browser extension support integrate directly with your existing browser-based workflows and automation scripts.
• •MCP support connect your browser capabilities to AI agents using the Model Context Protocol for standardized communication.

Limitations:

• •Requires your own AI logic — Browserbase provides the cloud browser infrastructure, but it has no built-in AI or decision-making. You must wire it to an LLM yourself. It is a building block, not a finished automation tool, so expect significant development work before anything runs.
• •Bot detection failures are common — Testing shows roughly 6 in 10 automation attempts fail on sites with CAPTCHA, login flows, or one-time passwords. Sites like LinkedIn, Google, and banking portals actively block headless browsers, making those workflows unreliable.
• •Minimum one-minute billing per session — Even if a browser session completes in 10 seconds, you are charged for a full minute. For workflows that open many short sessions (e.g. checking hundreds of pages), costs multiply quickly and unpredictably.
• •Multiple cost lines that add up — The Developer plan starts at $20/month, but proxy bandwidth, Search API calls, and Fetch API page calls are all billed separately. Real monthly costs are significantly higher than the headline plan price.
• •Layout-dependent selectors break silently — Without AI-native features, automations rely on XPath or CSS selectors that break whenever a target website updates its design, requiring constant maintenance.

Pricing:

• •Free $0/month, 3 concurrent browsers, 1 browser hour, 1,000 Search/Fetch calls.
• •Developer $50/month, 25 concurrent browsers, 100 browser hours, advanced stealth/identity features.
• •Startup $250/month, 100 concurrent browsers, 500 browser hours, 30-day session retention.
• •Enterprise Custom pricing, 250+ concurrent browsers, usage-based scaling.
