Graylog
Pros
- + Graylog Open is free with no volume restrictions — self-hosted logging without per-GB billing
- + Full data ownership and residency control; runs on your own hardware or private cloud
- + Long track record (project since 2009) with active community and solid documentation
- + Commercial editions let you stay on the same deployment as you grow into SIEM use cases
Cons
- - SSPL license is source-available, not OSI open source — restricts offering it as a service
- - Enterprise/Security/Cloud pricing is quote-based with no public calculator
- - Self-hosting carries real operational load: OpenSearch/Data Node, MongoDB, index and retention management
- - Audit logging and SIEM content sit in paid editions, not Open
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
