Free tools
Free tools, no signup
Small, honest tools built on the same probe fleet and certificate checks realuptime runs for paying customers. No account required, and each one shows exactly what it checked and how.
Is my website down?
Enter a URL and get a live status code and response time from a real check, right now.
SSL certificate checker
Enter a hostname and see its certificate's expiry date, issuer, and days remaining.
Why these are free
These tools run a single, one-off check, the kind of thing you might otherwise do with curl or a browser. They’re here because we already run the underlying checks for paying customers and it costs little to expose a public, honest, one-shot version. If you need the same check running continuously, with alerts, that’s realuptime’s actual product: see our outage tracker for 40 popular services we already watch, or start monitoring your own site.
