# Steel.dev

> Open-source browser API for AI agents, hosted or self-run

- Publishes its entire browser service under Apache-2.0, a credible middle ground between a hosted host and rolling your own
- Hosted version adds a session viewer, proxy egress and managed scaling; the open-source image runs on your hardware
- A cookbook of integrations with browser-use, CUA loops and LangChain is where most people meet it
