The short version
- Only Amplitude has a free tier, so it costs nothing to try first.
- 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; Datadog consumption-based pricing model makes costs hard to predict and can scale quickly
- They diverge on capability: Amplitude covers Event tracking, Datadog covers Infrastructure monitoring.
