Craft CMS Detector
Paste any URL and instantly see whether the site is built with Craft CMS — with the matched evidence.
We do not store the URL you audit. Want the full audit (performance / images / SEO / accessibility + real-browser speed test)? → run the full audit
Why check this
Confirm the platform first: CMS decides what can be changed and whether it is worth it.
What this is
Craft CMS is a flexible PHP CMS for editorial teams. Brand sites and publishing projects like its field layouts and multi-site tools. Confirmation lets you weigh plugins, image transforms and Twig compile cost against TTFB. Twig templates stay flexible until plugin image transforms quietly multiply derivative bytes.
How to tell from a public page
- [Craft CMS] A generator meta tag names Craft.
- [Craft CMS] Source or asset paths leave Craft CMS traces.
- [Craft CMS] Control-panel or asset URLs follow default cpresources patterns.
- [Craft CMS] Plugin scripts leave recognisable prefixes on public pages.
How to read the result
Confirm when generator or asset patterns reproduce; an agency proposal slide naming the CMS does not qualify. Absence can mean generator is off and asset prefixes are custom. Side-by-side CMS comparison tables contribute soft mentions. After a hit, review unused plugins and oversized transform presets.
What to do next
Prune plugins, cache template output, and constrain image transform sizes. CDN/protection can be checked via Cloudflare — open Cloudflare detector. Combined vitals return via run the full performance / images / SEO / accessibility audit on the home page. File Craft transform presets with the media team.

FAQ
How is Craft CMS detected?
From structural signatures in the public HTML and response headers (domains, paths, attributes, scripts). Every verdict lists how many times each pattern matched — nothing is guessed.
Can the result be wrong?
If only a bare brand keyword matches without structural evidence, we label it \u201clikely\u201d instead of \u201cconfirmed\u201d — we would rather under-report than cry wolf.
Do you save the URLs I check?
No. The audit runs inside the request and the URL you paste is not written to storage. There are no third-party tracking scripts on the page either, so no log of who checked what exists. Copy the result yourself if you want a record.
Can a website hide what it is built with?
Partly, but rarely completely. The HTML sent to your browser, the response headers, script paths and asset structure have to be exposed to work, so there is always something readable. Server-side code, build config and private APIs stay invisible. That is why this tool reports the evidence it found rather than claiming a full picture. No match does not mean the technology is absent.
