Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Healthchecks
- Focused on cron/heartbeat monitoring; it does NOT actively poll URLs for uptime like Pingdom/UptimeRobot
- No status page feature
- Manual setup requires configuring PostgreSQL/MySQL, SMTP, and a worker; Docker images are community-driven
- No synthetic transaction or multi-region checks
Prometheus
- No built-in dashboards UI; you must pair it with Grafana
- Long-term storage and horizontal scale need add-ons (Thanos, Cortex, Mimir)
- No logs, traces, or APM out of the box (metrics only)
- Steeper operational learning curve than turnkey Datadog
Bottom line
Both are a similar lift to self-host; choose Prometheus for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
