Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
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
VictoriaMetrics
- Primarily a metrics backend; needs Grafana for dashboards and vmalert for alerting
- No logs/traces/APM in the core product (separate VictoriaLogs project for logs)
- No public status page or synthetic uptime checks
- Assembling a full observability suite requires multiple components
Bottom line
Choose VictoriaMetrics if you want the lower-effort setup; choose Prometheus for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
