The short version

  • Only Weights & Biases 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; Weights & Biases pricing can be prohibitive for large teams without enterprise discounts
  • They diverge on capability: Datadog covers Infrastructure monitoring, Weights & Biases covers Experiment tracking.
