About

Browserbase is a cloud platform that lets AI agents and applications browse and interact with the web the way a human would. It addresses a common gap in automation: many websites have no public API, sit behind logins or CAPTCHAs, or change their interfaces frequently, which stops conventional scrapers and scripts. By providing fleets of managed headless browsers through a single API key, Browserbase turns the web into something programs can operate on directly.

The platform centers on cloud browsers, with supporting primitives around them: a Search API that finds relevant sites from a query, a Fetch API that converts any URL into HTML, JSON, or markdown, an Agents service for managed browser agents, Identity for authenticating agents past anti-bot systems, a Runtime for sandboxed code execution, a Model Gateway for using multiple AI models with one key, and Observability for debugging via replays, logs, and prompts. The company also maintains the open-source Stagehand SDK for browser automation. Browserbase reports that more than 10,000 companies use the platform, and its infrastructure is SOC-2 Type II compliant.

Key Features

Cloud browsers at scale: Programmatic access to fleets of headless browsers with 2 vCPUs each and isolated sessions, capable of running thousands of concurrent sessions.
Search API: A web search endpoint built for agents that returns relevant websites from a single query.
Fetch API: Retrieves any URL as LLM-ready HTML, JSON, or markdown for token-efficient context when a full browser session is unnecessary.
Agent Identity: Manages agent credentials and authentication so agents can pass logins, CAPTCHAs, and anti-bot checks; partnerships include Cloudflare, Stytch, Fingerprint, Vercel, and 1Password.
Stagehand: An open-source SDK combining Playwright-level browser control with AI primitives (`act`, `extract`, `observe`) that self-heal when pages change, plus action caching that reduces redundant model calls.
Functions: Deploy and run code next to the browser with under 5ms latency, without managing queues or schedulers.
Observability: Unified debugging across session replays, live view, rich logs, and prompts.

Pricing & Fees

  • Pricing: A Free plan at $0/month (3 concurrent browsers, 1 browser hour, 1,000 Search calls, 1,000 Fetch calls), a Developer plan at $20/month, a Startup plan at $99/month, and a custom-priced Scale plan via sales. Usage beyond included quotas is billed at per-unit rates, such as $0.12 per browser hour on Developer.
  • Free tier available: The Free plan includes 3 agent runs and $5 in model tokens for prototyping.
  • Open source: Stagehand and the Browse CLI are available as open-source npm packages (`@browserbasehq/stagehand`, `@browserbasehq/cli`), alongside SDKs and an MCP server.
  • Integrations: Works with major agent frameworks including LangChain, CrewAI, and Mastra, and supports HIPAA (BAA) and DPA on the Scale plan.

Who It's For

Browserbase is aimed primarily at developers and engineering teams building AI agents, automation workflows, or data pipelines. Typical users include AI engineers creating assistants that log into portals and fill forms, data teams extracting structured information from sites without APIs, and QA or product teams running continuous browser checks to catch broken flows. It serves industries such as AI and agent platforms, fintech, healthcare, go-to-market, and legal, supporting use cases like records verification, portal filings, document retrieval, data migration, and permissioned access to user-authorized accounts.
