Steel
Browser automationAn open-source browser API purpose-built for AI agents that need to use the web.
Steel is an open-source browser-as-an-API designed for AI agents. It manages sessions, proxies, and authentication, exposes the browser cleanly to an agent, and can be self-hosted or used hosted.
It overlaps with managed browser platforms but keeps the option of running the whole thing inside your own environment.
Where it's ideally used
A fit when agents need managed browser sessions and you want the choice between hosted and self-hosted.
Where it doesn't fit
Infrastructure rather than agent logic — you still bring the model and the decisions.
