GuardLabs Web-Audit Guardian ★ Featured
Continuous public-web-layer guardian — watches HTTP / size / multi-lang redirects / cyrillic drift / structure every 30 min. Self-hostable from $99 one-time.
What it does well
- Catches multi-language drift and truncation that uptime monitors and DAST scanners both ignore.
- Self-hostable tier is a one-time fee — runs as a systemd unit on any small VPS with no per-URL pricing.
- Live public timeline of incidents — including ones we caused — is verifiable proof, not marketing copy.
Where it falls short
- Not a vulnerability scanner — does not look for SQL injection, XSS, CSRF, or auth flaws.
- 30-minute check interval is fixed on Self-Hosted tier — sub-minute monitoring requires Pro+.
- Built around sitemap.xml as the source of truth — sites without a sitemap need manual URL list config.
