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
SigNoz
Pros
- + Usage-based pricing with published per-unit rates ($0.30/GB logs and traces, $0.10/mn metric samples) and no per-user or per-host billing
- + OpenTelemetry-native: no proprietary SDKs, so instrumentation does not lock you in
- + Logs, metrics, traces, APM, exceptions and alerts correlated in one ClickHouse-backed product
- + Self-hostable open-source community edition plus cloud regions in the US, EU and India with SOC2 Type II and HIPAA compliance
- + Worked pricing examples and a bill calculator published — costs are computable before you commit
Cons
- - No published uptime SLA below the Enterprise tier (from $4,000/month)
- - Self-hosted community edition makes storage, scaling, upgrades and backups your operational problem
- - Usage bills move with retention choices and noisy telemetry; the $49 entry tier shows a struck-through $199 base price
- - Narrower turnkey integration ecosystem than Datadog; RBAC is beta and audit logs/multi-tenancy are roadmap items
- - Migration tooling and dedicated Slack support are gated at spends above $999/month
