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

Fathom

  • Team plan requires minimum 2 users; cannot purchase single seat at team pricing
  • CRM field sync and deal view summaries available only on Business plan ($34/user/month) and above
