OpenTelemetry
Depends
Confidence: High
Adopt it if you run distributed systems and have engineers to own instrumentation and pipelines.
Comparison
OpenTelemetry vs SigNoz
OpenTelemetry and SigNoz both land on Depends.
SigNoz
Depends
Confidence: Medium
Buy if you're an engineering team comfortable with OpenTelemetry and some ops work who wants to cut Datadog-class bills.
| Compare | OpenTelemetry | SigNoz |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Microservices teams needing distributed tracing | Engineering teams ditching Datadog bills |
| Who it's not for | Solo devs on one monolith . a logging library is enough | Teams with nobody to run ClickHouse and upgrades |
| Privacy | Actively maintained project with a published 2024 security audit, but several recent DoS CVEs in language components and the Collector.⁷ | SOC 2 Type II claimed, but multiple 2026 CVEs (SQL injection, auth bypass) mean you must patch fast. |
| Support quality | No support data in sources | No user support evidence in sources |
| Public sentiment | Developers value vendor neutrality but consistently debate whether the setup effort and ecosystem complexity are worth it.⁴ | Users like the price and OpenTelemetry approach but report unstable log queries and UI rough edges in production.14 |
| Biggest gotcha | Instrumentation is free; ingestion and storage are not . one team pays $2,400/month sampling 1%³ | SQL injection CVEs in alert endpoints, unfixed until 0.142.1 |
