What detecting MySQL tells you about a site

Quick facts
Detection methodology for Databases
Database technologies that interact with the frontend ship their client SDKs as bundled JavaScript. Prisma's `@prisma/client`, Drizzle's `drizzle-orm`, Supabase's `@supabase/supabase-js`, Firebase's `@firebase/app` — each shows up as a `node_modules/<package>/` path in the sourcemap, with the exact version readable from the embedded `package.json`. The actual database server (Postgres, MySQL, SQLite) is not exposed to the browser by design.
FAQ
How do I check if a website is using MySQL?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. MySQL's fingerprints span response headers, asset URL prefixes, runtime globals and sourcemap paths, and the popup flags MySQL whenever any combination of them is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What MySQL version can Sourcemap Explorer detect?
MySQL ships as a hosted databases rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
Where can I read more about MySQL?

Open the popup on any page running MySQLand you'll see the exact version pulled from the bundled package.json when sourcemaps are exposed.
