FAQ
Common questions
How does the platform detector work?
It fetches the page HTML the same way a browser does and looks for platform fingerprints: WordPress leaves wp-content asset paths, Shopify loads from cdn.shopify.com, Next.js embeds a __NEXT_DATA__ payload, and so on. It also reads the generator meta tag and the Server response header, and spots common analytics scripts like GA4, Meta Pixel and Hotjar.
What do the confidence labels mean?
High confidence means we found a signature that is essentially unique to that platform, like Shopify's CDN domain. Medium and low confidence matches rely on weaker hints — for example an empty div with id="root" suggests a React app but cannot prove which framework built it.
Why did the detector find nothing on some sites?
Custom-built sites, heavily optimised builds that strip identifying markup, and sites behind aggressive bot protection can all come back empty. That result is itself a clue: it usually means a bespoke or unusual stack rather than an off-the-shelf builder.
