Runs on its own, L4 · Runs on its own: our agent signed up, got a token and did the core work without help. No checkpoint stopped it: sign-up took an email code with no bot check, and the token on the dashboard opened REST, BrowserQL, Puppeteer, the Agent Run API and the MCP server, each tried and working on the Free plan. A persisted session did not survive a reconnect, and profile creation failed with an unclear error. Paying needs a card at checkout our agent could not open, and cancelling or deleting the account both run through a web form with a required survey.

Steel is a cloud browser API that lets an AI agent run real Chrome sessions, scrape pages, take screenshots/PDFs, and store logins and profiles. An agent did almost all of this entirely on its own through the API, SDK, CLI, or official MCP server. The one place it needed a human-style browser step was getting in at all: signing up (an emailed link) and the first API key both come from the web dashboard, and deleting the organization left the underlying login account still active.
