Solid Detector
Paste any URL and instantly see whether the site is built with Solid — 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: Framework decides what can be changed and whether it is worth it.
What this is
SolidJS is known for fine-grained reactivity and less virtual-DOM overhead. Performance-sensitive marketing pages and dashboards are adopting it. Confirming `solid-js` package traces or `data-hk` hydration keys lets you judge bundling strategy and island boundaries. Fine-grained updates help only when bundles stay small and UI kits stay optional.
How to tell from a public page
- [Solid] Scripts or source maps include the `solid-js` package name.
- [Solid] Nodes carry `data-hk=` hydration keys.
- [Solid] Build output shows fine-grained update runtime characteristics.
- [Solid] Starter-template directory or manifest naming is recognisable.
How to read the result
Confirm when package names or hydration keys reproduce; English adjectives about reliable evidence are irrelevant. Absence can mean an extremely minified compile output. Other libraries that also use hk attributes deserve a second look. After a hit, check whether a large UI kit was pulled in unnecessarily.
What to do next
Keep components granular, avoid surplus client state, and verify hosting — often Vercel — via Vercel detector. Combined vitals return via run the full performance / images / SEO / accessibility audit on the home page. Prefer resumable defaults only when SolidJS markers are truly confirmed.

FAQ
How is Solid 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.
