Axiom review

Axiom is a strong pick for developer teams that log a lot and query selectively, and it ranks seventh because some admin features cost extra. The Personal plan is free and permanent, with 500 GB a month of data loading compute, 10 GB-hours of query compute, 25 GB of storage and 30-day retention. Axiom Cloud adds a $25 monthly platform fee plus usage, with no minimum commitment, an Always Free allowance of 1 TB of loading, 100 GB-hours of query and 100 GB of storage, and automatic volume discounts beyond that. Axiom describes a fully managed, schema-less event store with 95%+ compression and a schema-on-read design, so there are no indexes to manage and virtual fields handle transforms at query time. Queries use APL, which is powerful but new to most engineers. Enterprise controls are self-serve but priced separately: SAML SSO adds $100, RBAC $50 and Directory Sync $100.
