Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SonarQube

  • Advanced Security add-on uses custom pricing
  • Only private project lines of code count toward limits

Thanos

  • Several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • The compactor is a common source of operational trouble and must not run twice against the same bucket
  • Query latency over object storage is meaningfully higher than local Prometheus
  • Object storage costs and API request charges become real at high volume
