Open-Source & Self-Hosted Alternatives to Better Uptime & PagerDuty

Uptime monitoring and on-call alerting services charging steep monthly fees for basic ping checks.

Proprietary Pricing:$25 to $160+/month for heartbeat monitoring and incident response
Self-Hosted Cost:€3.79 - €14.28/month (VPS fixed)
Average Annual Savings:Save $600 - $18,000+/year

Why Migrate Away from Better Uptime & PagerDuty?

Paying $30+/mo for simple HTTP ping checks and SSL expiration alerts is unnecessary overhead. Self-hosted monitoring tools provide multi-protocol pings, SSL expiration timers, ping latency charts, and publicly hosted status pages at zero additional cost.
