Axiom
Event platform for logs and traces with a permanent free allowance on every plan and separate compute billing for queries.
- Error tracking and observability
- Yes
- $25/month platform fee for Cloud, plus usage, with no minimum commitment. The plan carries an always-free allowance of 1 TB loaded, 100 GB-hours of query compute and 100 GB stored.
- Two, both on AWS: US East 1 and EU Central 1. Axiom calls them edge deployments — you pick one per organisation and event data is stored at rest there, while the console stays at app.axiom.co. Datasets in one organisation can sit in different deployments. New ones are added on request rather than published as a roadmap.
Who it suits.
Small projects that want a real telemetry platform for nothing — 500 GB a month loaded with 30-day retention, permanently, is the most generous free allowance in this category.
Consider something else if…
Query compute is billed as its own meter in GB-hours, so an expensive dashboard costs money even when ingest is inside the allowance.

Pricing model
A platform fee plus three separate meters — data loaded, query compute in GB-hours, and stored GB — each with an always-free allowance included on every plan and automatic volume discounts above it.

When you exceed a cap
Billed, then paused per meter. Charges accrue past the Always Free allowance until they reach the spending limit you set, at which point Axiom stops the actions that cost money — and it stops them meter by meter: exhausting query compute halts queries and the monitors that depend on them while ingestion keeps running on an unspent data-loading allowance. Axiom says plainly that this can interrupt service.

- Usage and billing — Axiom Docs ↗
“When your accumulated charges reach your spending limit, Axiom automatically pauses actions that generate further costs. This can cause interruptions to your service. [...] if you have used up the query compute allowance included in your pricing plan, you can't run queries and your monitors can't query your data. At the same time, if you haven't yet used up the data loading allowance, you can still ingest data.”
