OpenObserve
Depends
Confidence: Medium
Buy if you ingest heavy log volume, have DevOps capacity to self-host or patch, and want Datadog-level features at a fraction of the cost.
Comparison
OpenObserve and SigNoz both land on Depends.
Buy if you ingest heavy log volume, have DevOps capacity to self-host or patch, and want Datadog-level features at a fraction of the cost.
Buy if you're an engineering team comfortable with OpenTelemetry and some ops work who wants to cut Datadog-class bills.
| Compare | OpenObserve | SigNoz |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | High-volume log teams bleeding money on Datadog | Engineering teams ditching Datadog bills |
| Who it's not for | Buyers needing genuine OSI open-source licensing, not open-core | Teams with nobody to run ClickHouse and upgrades |
| Privacy | Three published CVEs (SSRF, privilege escalation, unauthorized access); active advisory process and trust center exist.⁹ | SOC 2 Type II claimed, but multiple 2026 CVEs (SQL injection, auth bypass) mean you must patch fast. |
| Support quality | Reviewers report responsive team support | No user support evidence in sources |
| Public sentiment | Users praise cost, ease, and scale on Reddit, G2, and Product Hunt; a vocal minority resents enterprise feature gating.² | Users like the price and OpenTelemetry approach but report unstable log queries and UI rough edges in production.16 |
| Biggest gotcha | Open-core reality: some features require paid or enterprise licenses despite the public repo⁴ | SQL injection CVEs in alert endpoints, unfixed until 0.142.1 |
