The short version

  • Only Redis 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; Redis licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • They diverge on capability: PagerDuty covers Incident response, Redis covers In-memory data store.

  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases
