The short version

  • Only Deepgram has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog Logs complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale; Deepgram pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • They diverge on capability: Datadog Logs covers Log ingestion, Deepgram covers Flux speech-to-text.

Datadog Logs

  • Ingestion pricing of $0.10/GB can accumulate rapidly for high-volume logging environments

Deepgram

  • Pricing is entirely usage-based, so total cost can be harder to predict than flat subscription tools.
  • The Growth plan requires a minimum $4K/year commitment to unlock discounted rates.
  • Enterprise features and custom SLAs require a direct sales conversation rather than self-serve signup.
  • Some promotional per-minute rates are time-limited, meaning long-term pricing may differ from current promotional rates.
