VerdictDependsDepends
Best forMicroservices-heavy engineering teamsEngineering teams ditching Datadog bills
Who it's not forSmall teams wanting zero-ops observabilityTeams with nobody to run ClickHouse and upgrades
PrivacyOpen-source project with a public security page and disclosure process; one Snyk-listed flaw in a FIPS variant; no breaches reported.10SOC 2 Type II claimed, but multiple 2026 CVEs (SQL injection, auth bypass) mean you must patch fast.
Support qualityNo support evidence; community-maintained open source.No user support evidence in sources
Public sentimentDirect user reviews of the tracing tool are scarce in our sources; sentiment rests mostly on vendor comparisons and a small G2 sample.³Users like the price and OpenTelemetry approach but report unstable log queries and UI rough edges in production.14
Biggest gotchaFree software, not free to run: storage backends and trace volume drive real infrastructure cost.⁶SQL injection CVEs in alert endpoints, unfixed until 0.142.1
