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

Grafana Loki

  • Grafana Cloud Logs Pro plan includes only 30-day retention; retention beyond 30 days requires Enterprise plan with minimum $25,000 annual commitment
  • Open-source version requires self-hosting all infrastructure including storage and scaling
