Its status page records about six hours of Scrape API downtime in 90 days, and a bot check blocked our read of the terms and privacy policy.\n\n**Steel.** The hosted API has a public OpenAPI document, per-unit prices, $30 of starting credit and x402 payment for scrape, screenshot and PDF calls. The status page records three API or session-creation incidents of more than an hour in 90 days, and the documented CDP connection puts the API key in the URL.\n\n## Before you call either\n\n### Notte\n\n1. Send `Authorization: Bearer $NOTTE_API_KEY` to https://api.notte.cc. A person creates the key in the console at console.notte.cc first\n2. Stop every session when the task ends. Sessions close after 3 idle minutes or 15 minutes in total by default, and the Free plan caps a session at 15 minutes\n3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full\n4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you\n5. Download session replays within 24 hours. The recordings page says they are deleted after that\n\n### Steel\n\n1. Use `POST /v1/scrape` for pages you only need to read. It starts no session and costs $5 per 1,000 calls, or $0.01 a call by x402\n2. Release every session with `POST /v1/sessions/{id}/release` and set `inactivityTimeout`. Browser time bills by the minute, rounded up\n3. Build the CDP URL as `wss://connect.steel.dev?apiKey=\u003ckey\u003e\u0026sessionId=\u003cid\u003e` and keep it out of logs, because it carries the key\n4. Launch sessions end after 15 minutes at most, and `timeout` cannot be changed on a live session\n5. CAPTCHA solving and Steel's managed proxies on Launch need $10 of paid balance. Free credit does not count\n\n## Questions\n\n### Which is better for AI agents, Notte or Steel?\n\nSteel scores 70.4 (BB) on agent readiness against Notte's 63.2 (B), and leads in 4 of 7 scored categories.\n\n### Do Notte and Steel need an API key?\n\nNotte takes an API key or an OAuth sign-in. Steel needs an API key. An agent can also pay Steel per call over x402, with no account.\n\n### Can an agent call Notte and Steel without installing anything?\n\nYes. Notte has a hosted endpoint at https://api.notte.cc and Steel at https://api.steel.dev.\n\n### Are Notte and Steel open source?\n\nNo open-source release is listed for Notte. Steel is open source (Proprietary cloud service under Steel's terms. steel-browser and the Node and Python SDKs are Apache-2.0. The MCP server and the CLI are MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/notte-vs-steel.json, and with the fewest tokens: https://www.anchorterminal.com/compare/notte-vs-steel.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"notte\", \"b\": \"steel\"}`.
