About UpNimbus

UpNimbus — Uptime monitoring and status pages from the edge — free. Free to use, no trial, no watermark, and no account required to get started.

Why UpNimbus

Traditional uptime monitoring means servers, agents, and a bill that scales with your check frequency. UpNimbus runs checks on Cloudflare’s edge network on a cron schedule, so global monitoring costs almost nothing and starts in one click.

Start with instant one-shot checks — status code, response time, SSL certificate expiry, and full headers — then add scheduled monitors that remember their history and drive a public, KV-cached status page that stays up even when your app is down.

Free to use

Every tool here is free — no account required and no caps on the essentials. Create a free account to sync your history across devices (never your content or files), and a future Pro plan will add conveniences for power users. The free tools stay free, regardless.
