The short version

  • Only Thanos has a free tier, so it costs nothing to try first.
  • Each has a real cost: PagerDuty aIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: PagerDuty covers Incident response, Thanos covers Global query.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

PagerDuty

  • AIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost
  • Complex escalation policies require workarounds for scheduling patterns beyond basic weekly rotations
  • 5-user minimum requirement forces costs even for small teams, with forced Business tier upgrades adding $12,000+ annually for larger teams

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
