Free tools
Free diagnostic, recovery, SEO, and website-risk tools from Rescue404. Use them to understand problems, plan recovery, identify technical gaps, and make better maintenance decisions.
These are practical diagnostic utilities — not thin calculators or quizzes. Results are free, with no email gate. Use them to see why a URL is failing, why a browser says Not Secure, prepare for outages, verify backup readiness, estimate downtime impact, and inspect public SEO signals.
Paste a public URL. See why it is failing, or why a browser shows Not Secure — no login.
Public HTTP status, TLS expiry, DNS A/CNAME, redirect chain, and TTFB — paste a URL, no login. Plain-language diagnosis, not just up or down.
Use case: Emergency triage when a site will not load and you need to know whether DNS, SSL, redirects, or the origin failed.
