Zabbix
Pros
- + Free, no per-host or per-seat licensing — cost stays flat as monitored infrastructure grows
- + Deep protocol coverage: agent2, SNMP, IPMI, JMX, HTTP, synthetic checks, Kubernetes
- + 25 years of field-hardened releases with a disciplined LTS support schedule (7.0 LTS to June 2029)
- + Zabbix Cloud removes the ops burden without changing the tool; 5-day trial without a credit card
- + Open source under AGPLv3 with a documented API, Terraform provider and large template ecosystem
Cons
- - Steep learning curve — configuration UI, trigger syntax and template design need real investment
- - Zabbix Cloud drops values at random above the NVPS cap and disk only grows (once per 24h, never shrinks)
- - No published numeric uptime SLA or public region list for Zabbix Cloud; compliance certifications still in progress
- - Weaker on logs and distributed tracing than modern observability suites; self-hosting means you own the upkeep
Oh Dear
Pros
- + Every feature on every plan — no tiering of SSO, status pages, users, or API access
- + Two-location verification before firing alerts, which genuinely reduces false alarms
- + One site slot replaces uptime, SSL, broken-link, DNS, cron and Lighthouse tools at a predictable per-site price
- + EU-hosted (Belgium, ISO 27001 infrastructure) with full API and strong agency/reseller workflow
Cons
- - No free plan and no single-site tier below €15/month
- - Website/server monitoring only — no APM, metrics, logs, or host-level observability
- - Small vendor (2–10 people) with no published SLA for the monitoring service itself
- - Per-site cost is above bare uptime checkers; 200 sites costs €399/month
