✨ Highlights
Steel.dev is an open-source browser API that makes it easy to build AI apps and agents that interact with the web. Instead of building automation infrastructure from scratch, you can focus on your AI application while Steel handles the complexity.
Under the hood, it manages sessions, pages, and browser processes, allowing you to perform complex browsing tasks programmatically without any of the headaches:
- Full Browser Control: Uses Puppeteer and CDP for complete control over Chrome instances -- allowing you to connect using Puppeteer, Playwright, or Selenium.
- Session Management: Maintains browser state, cookies, and local storage across requests
- Proxy Support: Built-in proxy chain management for IP rotation
- Extension Support: Load custom Chrome extensions for enhanced functionality
- Debugging Tools: Built-in request logging and a UI to view/debug sessions with
- Anti-Detection: Includes stealth plugins and fingerprint management
- Resource Management: Automatic cleanup and browser lifecycle management
- Browser Tools: Exposes APIs to quick convert pages to markdown, readability, screenshots, or PDFs.

Three weeks from now, you'll want Steel Browser again. Will you remember where to find it?
Save it to your library and the next time you need Steel Browser, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
