Uptime Kuma Has a Free Monitoring Tool — Know When Your Sites Go Down Before Users Do

A solo developer launched his SaaS on a Friday evening. Saturday morning, his Stripe webhook endpoint was down. He lost 14 hours of signups before a customer emailed him. The Monitoring Gap Enterprise monitoring (Datadog, New Relic) costs $15-30 per host per month. For indie developers, that is often more than the server itself. Uptime Kuma is a free, self-hosted monitoring tool that checks your websites, APIs, and services and alerts you the SECOND something goes down.
