Every website encodes its visual language in CSS. UI Archive reads that code, normalizes it into structured tokens — colors, fonts, spacing, icons — and stores the result as a permanent public snapshot. No account. No paywall. GPL-3.0 licensed: anyone can self-host the full archive.
Web UI
Open
Snapshot history, token diff, icon archive, and export. Works from the browser — no install.
Start inspectingDesign decisions are made in public and discarded in private. A rebrand happens; the old palette disappears. A typeface gets swapped; no record remains. UI Archive keeps a record. The archive is open by default — not because open is a marketing position, but because an archive that isn't public isn't an archive.
Is an account required?
No. Paste a URL, inspect, browse — zero sign-up. No card, no email.
Are there usage limits?
No declared limits during open beta. Fair-use throttling applies to protect the service.
Is the API stable for production use?
Yes. The API is live with no key during open beta. Call it directly and start building.
What goes into the public archive?
Snapshots go into the public archive — that's the point. Only public pages are crawled; authenticated content is never archived.
Can I run my own instance?
Yes. GPL-3.0 on GitHub. Deploy your own instance, fork, or contribute.
