Steel Browser is an open-source browser API and sandbox that manages browser sessions, proxies, stealth, and lifecycle so developers can build AI agents and web automation without infrastructure work. It exposes a REST API and SDKs (TypeScript, Python, Rust, Go) and connects with Puppeteer, Playwright, Selenium, and computer-use agents.
Use cases
- run cloud browser sessions for AI agents
- scrape websites with stealth and proxy rotation
- convert web pages to markdown, screenshots, or PDFs
- connect Claude or Gemini computer use to a real browser
- maintain cookies and login state across automation runs
- solve CAPTCHAs during automated browsing
- self-host a browser automation API instead of building one
When to choose
- you need managed, scalable browser infrastructure for LLM agents or web automation
- you want anti-detection, proxies, and session persistence out of the box
- you want to self-host a browser API compatible with Puppeteer/Playwright/Selenium
When to avoid
- you only need simple local scraping with a single script
- you need a lightweight headless browser library rather than a full service
- you require a fully stable GA product - it is still in public beta
