Where each one falls short

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

Axiom

  • No self-hosted or air-gapped deployment option for compliance-sensitive workloads
  • Vendor lock-in due to APL (Axiom Processing Language) not transferring to other platforms
  • Proprietary storage format limits data portability and external analytics access
  • Complex pricing model with multiple cost dimensions (ingestion, compute, storage) makes budgeting difficult at scale
  • Limited ecosystem integration; does not integrate deeply with existing observability stacks like Grafana for metrics and Jaeger for traces

Splunk Enterprise

  • Splunk Platform and Enterprise Security offerings carry no published rate and require contacting sales for a quote
  • Four different pricing models are offered (activity, ingest, workload and entity based) and the applicable one depends on the product purchased
  • Published Observability Cloud rates start at $15 per host per month and are billed annually rather than monthly
  • Volume discounts are not published and require direct consultation with sales
