About World Wide Uptime

World Wide Uptime is a free, privacy-first uptime checker. Put a domain in, get a full multi-region report out — response times, status codes, SSL info, redirect chain and DNS records.

We built it because every "free monitoring tool" eventually walks you into a credit card form or a sales call. Sometimes you just want to know if your site is up from Tokyo right now, with no signup, no tracking, no upsell.

Principles

• Free forever for the one-shot checker. No paywall.
• Private by default. History lives in your browser. We don't log domains.
• Depth over fluff. We show you timings, headers, certs and DNS — not just a green dot.
• Open. Public JSON API. SVG uptime badges. Engineers should be able to script us.
