Summary
Detects web technologies across 50+ categories including CMS platforms, JavaScript frameworks, analytics tools, and CDN providers. Works like Wappalyzer but exposed as an MCP server you can query from Claude. Point it at any URL and it returns structured data about what's powering the site. Runs as a hosted service at tech-enrichment.api.klymax402.com and uses x402 micropayments in USDC, so you pay per detection request rather than subscribing. Useful when you're researching competitors, auditing client sites, or need to quickly fingerprint a tech stack without manually inspecting source code and network requests.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.
