by Steel · steel.dev

Checked 2026-10-17 on Steel's own pages. Anything we could not confirm says “not verified”.

What is Steel? Browser API for agents. Steel Browser is open source (Apache-2.0); Steel Cloud adds hosted sessions, proxies, captcha solving and longer sessions on paid plans.

How an agent uses it: An official MCP server gives MCP clients a cloud Chrome that can read pages, fill forms and hand control to a human for logins.

Best for: Teams that want an open-source browser API they can self-host, with a hosted cloud for production.
