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; FullStory free tier limited to 30,000 sessions per month, no 5,000+ monthly active user sites
  • They diverge on capability: Amplitude covers Event tracking, FullStory covers Session replay.
