The short version

  • Only Splunk has a free tier, so it costs nothing to try first.
  • Each has a real cost: Elastic Stack self-managed deployment requires licensing based on node count and RAM usage; Splunk no prices are published on any plan; every model requires contacting sales for an estimate
  • They diverge on capability: Elastic Stack covers Log analytics, Splunk covers Log aggregation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Elastic Stack

  • Self-managed deployment requires licensing based on node count and RAM usage
  • Serverless option has pending features including traffic filtering and bring-your-own-key encryption
  • Hosted deployment requires custom resource configuration for cluster management
  • Pricing models differ significantly across Hosted, Serverless, and Self-managed options

Splunk

  • No prices are published on any plan; every model requires contacting sales for an estimate
  • Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
  • Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
  • Security, observability and platform are priced separately
