The short version

  • Each has a real cost: Amplitude metered on event volume, so instrumenting more of a product raises the bill even if the audience does not grow; Redis licensing changed from BSD to AGPL in 2025, impacting open-source usage
  • They diverge on capability: Amplitude covers Event tracking, 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.

Amplitude

  • Metered on event volume, so instrumenting more of a product raises the bill even if the audience does not grow
  • The free plan covers 2M events a month
