The short version

  • Only Readyset has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog consumption-based pricing model makes costs hard to predict and can scale quickly; Readyset pricing requires contacting sales team, making cost planning difficult
  • They diverge on capability: Datadog covers Infrastructure monitoring, Readyset covers Automatic Query Optimization.
