Usage statistics go to Google by default until you pass `--no-usage-statistics`.\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### Chrome DevTools MCP\n\n1. Pass `pageId` on every page tool. Call `list_pages` first to get it\n2. Start with `--slim` for plain browsing, or turn off categories you don't need\n3. Run with `--isolated` for untrusted sites. The default profile persists between runs\n4. Use `filePath` on large outputs such as traces and snapshots to keep them out of context\n5. Add `--no-usage-statistics` if the operator hasn't agreed to Google telemetry\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, Chrome DevTools MCP or Selenium?\n\nChrome DevTools MCP scores 77 (BB) on agent readiness against Selenium's 73.6 (BB), and leads in 3 of 7 scored categories. Selenium leads on reliability.\n\n### Can an agent call Chrome DevTools MCP and Selenium without installing anything?\n\nChrome DevTools MCP runs on your own machine, with no hosted endpoint listed. No hosted endpoint is listed for Selenium.\n\n### Are Chrome DevTools MCP and Selenium open source?\n\nYes. Chrome DevTools MCP is open source (Apache-2.0). Selenium is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/chrome-devtools-mcp-vs-selenium.json, and with the fewest tokens: https://www.anchorterminal.com/compare/chrome-devtools-mcp-vs-selenium.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"chrome-devtools-mcp\", \"b\": \"selenium\"}`.
