Website tech stack checker
Check a website's tech stack
Run one report for frontend frameworks, CMS clues, analytics scripts, hosting, DNS, headers, SSL, registrar, contact paths, and site-age signals.
Try:
What this checks
- Frontend and CMS fingerprints
- Hosting, CDN, DNS, SSL, and registrar clues
- Builder, contact, and age evidence when they explain the result
How I treat the evidence
The result is based on public evidence. I prefer showing the clue over pretending the guess is certain.
For sales research or rebuild work, the useful part is often the combination: framework plus host plus CDN plus visible services.
Why do some sites show few technologies?
Some sites bundle, proxy, or strip identifying code. That is a real signal too: the public stack is harder to inspect.
What should I do after a lookup?
Use the full report to compare domains, save promising leads, or check whether a site matches your rebuild or vendor-audit criteria.
