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**Selenium.** Selenium is stable, Apache-2.0 software on 4.51.0 with bindings in five languages, CI passing on trunk, an llms.txt and an agent guide added in September 2026. It has no MCP server of its own, Selenium Manager sends usage statistics by default, and Grid accepts unauthenticated sessions unless a username and password are set.\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### Selenium\n\n1. Install with `pip install selenium` (Python 3.10 or later) and let Selenium Manager fetch drivers. Do not set driver paths\n2. Use `WebDriverWait` with expected conditions, never fixed sleeps, and do not mix implicit and explicit waits\n3. Set `SE_AVOID_STATS=true` to stop Selenium Manager sending usage statistics\n4. Point coding agents at https://www.selenium.dev/llms.txt. Most Selenium 2 and 3 era examples use removed APIs\n5. Set `--username` and `--password` before exposing a Grid beyond localhost. Check `http://localhost:4444/status` before creating sessions\n\n## Questions\n\n### Which is better for AI agents, Notte or Selenium?\n\nSelenium scores 73.6 (BB) on agent readiness against Notte's 63.2 (B), and leads in 5 of 7 scored categories. Notte leads on agent ergonomics and security \u0026 auth.\n\n### Can an agent call Notte and Selenium without installing anything?\n\nNotte has a hosted endpoint at https://api.notte.cc. No hosted endpoint is listed for Selenium.\n\n### Are Notte and Selenium open source?\n\nNo open-source release is listed for Notte. Selenium is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/notte-vs-selenium.json, and with the fewest tokens: https://www.anchorterminal.com/compare/notte-vs-selenium.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"notte\", \"b\": \"selenium\"}`.
