Wappalyzer

Wappalyzer Metadata API

The four anonymous, unauthenticated technology and category reference endpoints on the v2 host — the technology directory (7,281 entries), a single technology profile, the category directory (106 entries) and a single category with its member technologies. Absent from the published contract; located from the provider's own open-source MCP server and confirmed live on 2026-08-14. Consumes no credits and requires no API key.
