Highlight.io
Pros
- + One stack for session replay, errors, logs, and traces with OpenTelemetry-based instrumentation and cross-signal correlation
- + Genuinely usable free tier: 500 monthly sessions and up to 15 seats at $0/month
- + Fully self-hostable from the public repository (Docker hobby stack), keeping session data on your own infrastructure
- + Strong docs for a vendor: architecture notes, self-hosting guides, changelogs, telemetry disclosure
- + Acquired into LaunchDarkly with the founders leading observability there, so the hosted product has a defined continuation path
Cons
- - Standalone product is being absorbed: highlight.io serves LaunchDarkly's site and cloud accounts are being migrated
- - Open-source repository's final community support date is still unannounced, so self-hosters face an uncertain maintenance horizon
- - Thin pricing ladder: nothing between the free tier and $800/month Business, with per-type usage overages and conflicting published quotas
- - No published infrastructure SLA, region map, or uptime record for the hosted product
- - Self-hosting means operating a multi-service stack (database, queue, collectors) with no managed middle tier
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
