Instatus vs Gatus
A highly customizable monitoring solution that provides automated status pages, extensive alerting options, and detailed testing capabilities for your services and infrastructure Here is how Gatus ($0/mo open source) stacks up against Instatus ($35/mo) across cost, hosting, data privacy, and real-world trade-offs.
Gatus is a verified Apache-2.0-licensed open-source replacement for Instatus. Switching from Instatus ($35/mo) saves $420/yr per solo seat, or $2,100/yr for a 5-person team. Deployment: Runs on Self-host.
The catch: It is configuration-driven and normally probes from one place, so Pingdom's global probe network and recorder-style transaction checks are the major losses.
