How do I know a detection is right?

Every line carries its evidence: whether it came from the HTML or the JavaScript, which indicator matched, and the files it turned up in. If we can't point at where something came from, it doesn't get listed.

Can I keep what it finds?

Save to folder files the site in your workspace with its screenshot, favicon, detected stack and your own tags attached — so it's searchable next to everything else you've saved, and the breakdown is still there months later.

Can I share an analysis?

Yes. Every analysis gets its own permanent page on save.design — screenshot, stack and detection log — and the link works for anyone you send it to.

Analyze is one part of Save Design.

Save Design is the workspace behind the analyzer. Save a breakdown and its stack is saved with it — so the reference is still findable by framework, library or font months later.
