updated this year

Free, open source website technology detection. Identify any site's full tech stack from its URL — CLI, library and MCP server for Claude, Claude Code, Codex and ChatGPT. No API key, no credits, no subscription.

Code-only MCP server: no hosted endpoint, so you install and run it yourself. It is not probed, graded or counted in our reachability statistics.
