What it does
Axiom is a managed telemetry and event-data platform for collecting, storing, and querying logs, traces, metrics, and events. It combines EventDB for timestamped event data with MetricsDB for high-cardinality time series, a browser console for visualization and monitoring, APL and MPL query languages, and a REST API.
Axiom brings application and infrastructure telemetry into a shared workspace. Its documentation describes EventDB for event data and MetricsDB for high-cardinality metrics; the console supports exploration, visualization, and monitoring. A practical first step is to create an account and send a small stream of events through the documented REST API, then query the resulting dataset in the console. The API also supports querying data and managing resources, so teams can automate ingestion and parts of their observability workflow.
The permanent Personal plan is free and has published monthly usage allowances and 30-day retention. Axiom Cloud adds a platform fee and usage charges, with included allowances and optional add-ons. Check current limits against expected ingestion, query compute, storage, and retention needs before routing production telemetry. The exact paid cost depends on usage and chosen options. Vendor claims about scale, compression, and cost were not independently tested.
Strengths
- Combines logs, traces, metrics, and events in one observability platform.
- Offers a permanent no-charge Personal plan with published usage allowances.
- Provides a REST API for ingesting and querying data and managing resources.
Watch out for
- The free Personal plan has usage allowances and 30-day retention limits.
- Axiom Cloud adds platform and usage charges, so the cost depends on workload and selected add-ons.
Best for
- Developers and operations teams seeking a shared platform for logs, traces, metrics, and event data.
- Individuals and small projects that fit the Personal plan's allowances.
- Teams that want to integrate telemetry workflows through a REST API.
