Browserbase

Browserbase is a Web and API platform for developers and AI agent teams that need reliable, high-performance serverless headless Chrome for production web automation.

Key capabilities include:

• Cloud browser sessions over WebSockets for automations that read and write on websites, handle form flows, scrape pages, take screenshots, and generate PDFs.
• Framework support and SDKs for Playwright, Puppeteer, Selenium, plus native Node.js and Python SDKs and support for uploads, downloads, and browser extensions.
• Stealth features such as managed CAPTCHA solving, residential proxies, and fingerprint management for workflows that need to reduce bot friction.
• Observability and control with Session Inspector, recordings, logs, command capture, and Live View for real-time human-in-the-loop intervention.

Pricing: offers a free plan ($0/month), with paid plans starting at $20/month (Developer), $99/month (Startup), and a custom-priced Scale tier, plus usage-based overage charges for things like browser hours and proxy usage.

What makes it notable: it combines a scalable headless browser fleet with serverless Browserbase Functions (deploy Playwright or Stagehand automations as API-invokable workflows), plus Contexts API for persisting cookies and localStorage across sessions and integrations with agent frameworks such as crewAI and LangChain.
