Made a free tool for quick website security audits. Paste a URL, get a letter grade.
What it checks:
- SSL cert validity + days until expiry
- Security headers (HSTS, CSP, XFO, XCTO, Referrer-Policy, Permissions-Policy)
- DNS config (A, AAAA, MX, SPF records)
- TTFB response speed

The individual checks are also available as API endpoints you can use in monitoring scripts or cron jobs:
curl http://5.78.129.127/api/ssl/yourdomain.com
curl http://5.78.129.127/api/dns/lookup/yourdomain.com
Free, no signup. What checks would you add?

This is terrible for privacy due to cleartext HTTP. At minimum fix your TLS before spamming further, please.
