Steel API

Steel (https://steel.dev) is an open-source browser API purpose-built for AI agents.

It offers endpoints for various browser actions and session management, enabling agents to navigate the web for information over long running browser sessions.

Key Capabilities:

  • Control fleets of browser sessions in the cloud via API or Python/Node SDKs
  • Easily extract page data as cleaned HTML, markdown, PDFs, or screenshots
  • Access data behind logins with persistent cookies and automatic sign-in
  • Render complex client-side content with JavaScript execution
  • Bypass anti-bot measures with rotating proxies, stealth configs, and CAPTCHA solving
  • Reduce token usage and costs by up to 80% with optimized page formats
  • Reuse session and cookie data across multiple runs
  • Debug with ease using live session viewers, replays, and embeddings

Target Audience:

  • AI engineers and developers working with online LLMs
  • Users with their own infrastructure looking to offload browser hosting operations
  • Users who need to scrape the web for information
  • QA teams who need to test web applications
