Tool profile
Observability platform for logs, traces, metrics, and event data with fast querying and long retention.
Engineering teams centralizing high-volume logs without host-based pricing
Axiom is a cloud observability datastore for logs, traces, metrics, and events with a usage-based pricing model pitched as self-serve enterprise (SSO/RBAC as paid add-ons).
Per axiom.co/pricing (March 2026), Personal is free forever with no credit card, 30-day retention, and marketing copy citing up to 500 GB monthly data ingest for evaluation/small projects. Axiom Cloud paid usage starts at $25/month as a platform fee with additional meters for data loading, query compute (GB-hours), and storage; the interactive estimator example shows $0.030/GB storage pricing on a sample configuration and references Always Free allowances for certain included GB tiers on paid orgs. Enterprise security add-ons list SAML SSO +$100/mo, Directory Sync +$100/mo, Audit Log +$50/mo, and RBAC +$50/mo on the same page.
Credits language appears (1 credit ≈ $1 default) for data loading and query compute ladders with automatic volume discounts as usage grows.
Compare Datadog and New Relic for full-platform APM bundles; compare Grafana Loki/Tempo stacks for DIY cost control; compare Honeycomb for high-cardinality tracing focus.
Quick fit
Editorial take
Axiom's public pricing is more transparent than many observability vendors, but it is still a platform fee plus multiple usage meters. The catalog needs to keep that mental model intact instead of flattening everything into a single per-GB number.

Apache Kafka

Open-source distributed event streaming platform for high-throughput pipelines, pub/sub, and stream-processing ecosystems.
Choose Kafka when replayable event streams and ecosystem breadth matter more than the lightest possible operational footprint.
Pricing snapshot
Axiom's public pricing centers on two tracks: Personal at $0 with 30-day retention for evaluation and small projects, and Axiom Cloud starting with a $25 per month platform fee plus separate usage charges for data loading, query compute, and storage. The paid product is explicitly metered rather than bundled into one all-inclusive observability seat price.

Runtime security toolkit for modern applications and AI systems that helps teams enforce quotas, block bots, prevent prompt abuse, and ship app-level protections in code.
Closer to application-runtime security and abuse-prevention tooling than to classic perimeter appliances.
