Quickstart
1. Create an account
Open Sign up. Tick Terms and Privacy. Confirm the email if one is sent.
2. Check a public app you own
Open Check. Paste a live https:// URL. Tick the box that you own the app or have permission to test it.
You get one of:
| Verdict | Meaning |
|---|---|
| Ready | No blockers. Small notes (SEO, modest TTFB) can wait. |
| Fix first | Warnings: missing HSTS/CSP, a same-origin script 404, a live URL 5xx on the launch gate, a certificate inside 14 days. |
| Do not launch | Blockers: public keys, 5xx/down homepage, invalid TLS, certificate inside 7 days. |
The scorecard reason is the first blocker or warning in plain language, not a score.
Free accounts get 10 new checks per month. The same URL within 24 hours reuses the last result. Demo shows a canned result with no live request.
3. Optional next steps
- Watch that URL on a schedule.
- Connect GitHub when you want source scans and a launch gate.
- Install an SDK when you want visitor errors and traffic on an app you own.
