The short version

  • Each has a real cost: Readyset pricing requires contacting sales team, making cost planning difficult; Redis licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • They diverge on capability: Readyset covers Automatic Query Optimization, Redis covers In-memory data store.

Where each one falls short

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

Readyset

  • Pricing requires contacting sales team, making cost planning difficult
  • Specific pricing tiers not disclosed publicly
  • Requires cache size estimation for cost calculation
  • Limited to read query caching, does not address write performance

Redis

  • Licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • All data must fit in memory, limiting scalability to available RAM
  • No built-in support for multi-tenancy
  • Limited transaction support compared to traditional databases
