Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Beszel
- No network device or SNMP monitoring
- Alerting options are basic compared to Zabbix or Checkmk
- No long-term data retention tuning or downsampling for historical data
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
Choose Beszel if you want the lower-effort setup; choose Prometheus for the larger community and ecosystem. Prometheus has seen more recent development. Open each guide below for deploy steps and the full feature gap.
