  • Only Logstash 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; Logstash logstash's source is dual licensed: code outside the x-pack directory is Apache License 2.0, but code inside x-pack (which carries several of Logstash's monitoring and management features) is licensed under the Elastic License, not a fully open source license
  • They diverge on capability: Datadog Logs covers Log ingestion, Logstash covers Data ingestion.
