What Wappalyzer is
Open a site, click the icon, and you see the stack: the CMS, the JavaScript framework, the analytics, the CDN, sometimes the email and payment services.
For a studio that is competitive research in one click — you learn what a prospective client already runs on before the first call, and what a competitor chose when they rebuilt.
Good for
- Finding out what a prospective client’s site is built on
- Checking what a competitor migrated to
- Identifying a CMS before quoting on work with it
Worth knowing
- Detection is inference from what the page exposes, so it is a strong hint, not proof.
- Bulk and API use is a paid feature; the extension itself is the free part.
