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
Zabbix
- Setup and configuration are complex; steep learning curve (database, server, frontend, proxies)
- Dated UI compared to modern SaaS dashboards
- No SaaS/managed tier from the project itself
- APM/tracing and modern log analytics are weaker than Datadog's offering
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.
