Browserbase (browserbase.com) is cloud-hosted headless browser infrastructure built specifically for AI agents and large-scale web automation, removing the need to provision, scale, or anti-detect a fleet of browsers yourself. Developers connect to Browserbase's serverless cloud through Playwright, Puppeteer, Selenium, or the company's own open-source Stagehand framework, and every session runs in an isolated, sandboxed environment with stealth and proxy handling built in.
AI and ML engineers building web-capable agents, automation and RPA developers, and data teams doing large-scale web extraction make up Browserbase's core user base, alongside QA teams running browser tests at scale. The company reports processing tens of millions of browser sessions and counts organizations including Microsoft, Amplitude, Ramp, Clay, and Lovable among its users, reflecting real production adoption rather than purely experimental usage.
How Browserbase Works
A developer's automation code โ written in Playwright, Puppeteer, Selenium, or natural language through Stagehand โ connects to a Browserbase session instead of launching a local browser, and the platform handles the underlying Chrome instance, proxy rotation, and anti-bot fingerprinting automatically. Stagehand, Browserbase's own AI-powered automation SDK, lets an agent describe an action in plain language rather than writing brittle CSS selectors, and it self-heals when a page's structure changes rather than breaking outright. Every session includes a live view and a full recording, so a developer or an agent debugging its own run can watch exactly what happened step by step instead of guessing from logs alone. Native MCP support also exposes Browserbase directly as a tool for LLM-driven agent frameworks, and Browserbase Functions let automations and agents be deployed and run directly on the platform to cut network latency.
Key Features
- Serverless cloud browser sessions: spin up isolated, sandboxed Chrome instances instantly without managing servers or a browser fleet
- Stagehand AI automation SDK: Browserbase's own open-source framework for driving a browser using natural language instead of manual selectors
- Built-in stealth and anti-detection: fingerprinting evasion and stealth configuration to reduce bot-detection blocks during automation
- Integrated residential proxy network: proxies included and configurable per plan for higher-success, geographically distributed requests
- Automatic CAPTCHA solving: handles common CAPTCHA challenges automatically as part of a session, without a separate solving service
- Session live view and recording: watch an agent's actions in real time or replay a full recording afterward for debugging
- MCP support: native Model Context Protocol integration makes Browserbase directly usable as a tool by LLM agent frameworks
- Framework compatibility: drop-in replacement for local Playwright, Puppeteer, and Selenium setups with minimal code changes
- SOC 2 Type II and HIPAA compliance: enterprise-grade security certifications with Business Associate Agreements available on request

Who Should Use Browserbase?
Developers building AI agents that need to genuinely browse the web โ clicking, filling forms, navigating multi-step flows โ rather than just fetching static pages are the strongest fit for Browserbase, since Stagehand and the built-in stealth and CAPTCHA handling solve problems a basic scraper doesn't touch. The Free plan is enough to prototype a single agent workflow and see how Stagehand behaves before committing to a paid tier. Developer suits individual builders and small teams running real but modest-volume automations, while Startup is where most production applications land once concurrency and monthly browser hours need to scale meaningfully. Scale exists for organizations running large agent fleets or high-volume automation pipelines that need custom infrastructure, verified agent identity, and dedicated support. Teams in regulated industries will also want to weigh Browserbase's SOC 2 Type II and HIPAA compliance options, since those matter for handling any sensitive data during automated browser sessions.
Frequently Asked Questions
What problem does Browserbase solve for AI agents?
Browserbase provides cloud-hosted, isolated browser sessions so AI agents and automation scripts can interact with real websites without a developer having to provision, scale, or maintain their own browser fleet, proxy network, or anti-bot fingerprinting setup.
Is there a free way to try Browserbase?
Yes, the Free plan includes 3 concurrent browsers, 1 browser hour, and 3 agent runs with no cost, enough to prototype a workflow before deciding whether to upgrade to the Developer plan at $20/month.
What is Stagehand, and do I have to use it?
Stagehand is Browserbase's own open-source AI automation SDK that lets an agent describe browser actions in natural language instead of writing selectors, with self-healing behavior when a page's structure changes. It's optional โ Browserbase also works as a drop-in replacement for standard Playwright, Puppeteer, or Selenium code without using Stagehand at all.
Does Browserbase handle CAPTCHAs automatically?
Yes, automatic CAPTCHA solving is included on the Developer plan and above, so an agent hitting a CAPTCHA challenge during a session doesn't need a separate third-party solving service integrated into the workflow.
Can I connect Browserbase directly to an LLM agent framework?
Yes. Browserbase offers native MCP (Model Context Protocol) support, which exposes it as a tool that LLM-powered agent frameworks can call directly to drive real browser sessions as part of a larger agentic workflow.
