steel.dev
Steel is a cloud browser infrastructure platform for AI agents and automation developers. It lets you launch and control remote browser sessions, scrape content, manage files/profiles/credentials, and connect automation frameworks like Playwright or Puppeteer.
Steel exposes a REST API at `https://api.steel.dev/v1`, a CDP-over-WebSocket browser connection at `wss://connect.steel.dev`, and a `steel` CLI; all use a Steel API key.

Sign in at Steel Dashboard, open Settings → API Keys, click Create API Key, name it, and copy the value. The docs recommend storing it in STEEL_API_KEY; for direct REST calls send it in the steel-api-key header, and for CDP browser connections pass it as the apiKey query parameter on wss://connect.steel.dev.
