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
Vector
Pros
- + Free at any scale: no license fees, no ingest caps, no feature tiers
- + One binary for the whole pipeline: 47 sources, 17 transforms, 61 sinks
- + Pre-egress control plane — redact, sample, aggregate, and fan out before data leaves your network
- + Rust reliability engineering: disk buffers, acknowledgements, per-component delivery guarantees
- + Battle-tested at scale (public users at 500+ TB/day) with active Datadog-backed maintenance
Cons
- - VRL and pipeline configuration are a real learning investment; advanced pipelines become software projects
- - Open source support is community-only — no SLA, no guaranteed response
- - Roadmap gravity favors Datadog's ecosystem; deepest integrations land there first
- - Frequent releases with occasional breaking config changes require planned upgrades
- - Traces support exists but is less mature than the logs and metrics paths
