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

Humanloop

No published pricing for standard plans; customers must contact sales for quotes
Billing based on logs created per API call, making costs unpredictable without usage estimates
Separate charges apply from AI providers (OpenAI, Anthropic, etc.) using customer's own API keys, adding external costs
