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
Sentry
Pros
- + Industry-standard error grouping and stack traces with code context
- + Free Developer plan at $0 including error monitoring and tracing
- + Framework SDKs make setup a one-afternoon job
- + EU data residency (Frankfurt) at no extra cost on all plans
- + Covers tracing, session replay, release health, cron and uptime monitors in one subscription
- + Self-hostable server code for teams that must run their own stack
Cons
- - Usage-based overage on errors, spans, and replays can spike bills unexpectedly
- - Real setup work needed to control noise (grouping, filters, sampling)
- - No public uptime SLA on self-serve plans
- - No APAC data region; some account metadata stays in the US even on EU orgs
- - Self-hosted deployment is operationally heavy and the license is not plain OSI open source
