How is Browserbase different from Firecrawl?

Firecrawl is optimized for content extraction — it scrapes pages and returns clean data. Browserbase provides a full browser environment for interactive automation — your agent can click buttons, fill forms, log into websites, scroll, and navigate complex single-page applications (SPAs). Browserbase gives you a real browser, Firecrawl gives you the text from a page.

Which automation frameworks are supported?

Browserbase sessions expose a CDP (Chrome DevTools Protocol) WebSocket URL, which is compatible with all major browser automation frameworks: Playwright, Puppeteer, Selenium WebDriver, and any tool that supports CDP connections. Simply point your framework at the connectUrl returned when creating a session.

What does the free tier include?

The free tier includes 1 browser hour, 1 concurrent browser session, and 7 days of data retention. No credit card required. For production workloads, paid plans start at $20/month (Developer) with more browser hours and concurrent sessions.

About Browserbase MCP Server

Connect your AI agent to Browserbase — the serverless platform for running headless cloud browsers at scale.

LangChain's ecosystem of 500+ components combines seamlessly with Browserbase through native MCP adapters. Connect 4 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

What you can do

Create Sessions — Spin up isolated Chromium browser sessions in the cloud. Each session returns a CDP (Chrome DevTools Protocol) WebSocket URL for connecting Playwright, Puppeteer, or Selenium
List Sessions — Monitor all active, completed, or errored browser sessions across your account
Get Session Details — Check status, connection URLs, pages visited, and duration of any session
Stop Sessions — Terminate running sessions to free resources

The Browserbase MCP Server exposes 4 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Browserbase MCP Tools for LangChain (4)

These 4 tools become available when you connect Browserbase to LangChain via MCP:

create_browser_session

The session provides a connectUrl (CDP WebSocket) that can be used with Playwright, Puppeteer, or Selenium to control the browser programmatically. Default timeout is 300 seconds. Create a new cloud browser session. Returns a CDP WebSocket URL for connecting automation frameworks like Playwright or Puppeteer

get_browser_session

Useful for monitoring active sessions. Get details of a specific browser session by its ID

list_browser_sessions

Filter by status: RUNNING, COMPLETED, ERROR. List all active browser sessions in your Browserbase account

stop_browser_session

Any unsaved state in the browser is lost. Stop a running browser session by its ID

Example Prompts for Browserbase in LangChain

Ready-to-use prompts you can give your LangChain agent to start working with Browserbase immediately.

"Create a new browser session so I can automate a login flow."

"Show me all my running browser sessions."

"Stop browser session sess_abc123."
