Datadog
Depends
Confidence: High
Buy it if you run a mid-to-large engineering org with complex infrastructure and budget for usage-based bills.
Comparison
Datadog vs SigNoz
Datadog 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 | Datadog | SigNoz |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Mid-to-large engineering orgs | Engineering teams ditching Datadog bills |
| Who it's not for | Small teams or side projects on a budget | Teams with nobody to run ClickHouse and upgrades |
| Privacy | No confirmed platform breach in reviewed sources; agent components carry published CVEs and a 2016 incident is documented.10 | SOC 2 Type II claimed, but multiple 2026 CVEs (SQL injection, auth bypass) mean you must patch fast. |
| Support quality | No support evidence in reviewed sources | No user support evidence in sources |
| Public sentiment | Users praise the unified visibility and integration depth, but cost is the loudest complaint across Reddit and review sites.¹ | Users like the price and OpenTelemetry approach but report unstable log queries and UI rough edges in production.16 |
| Biggest gotcha | Multi-dimensional billing: hosts, logs, APM, synthetics each metered separately⁵ | SQL injection CVEs in alert endpoints, unfixed until 0.142.1 |
