Axiom alternatives: 6 open-source picks
Axiom costs $25/mo — $300 a year. These 6 alternatives replace it for $0, led by OpenObserve, HyperDX and VictoriaLogs. All 6 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Logs, traces and metrics in one binary; your disk gets the invoice.
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup, or a single binary/Docker container; Helm plus external services for HA
dataTelemetry is stored as Apache Parquet on local disk or object storage; single-node metadata defaults to SQLite, while HA uses PostgreSQL and NATS.
the catch vs AxiomIt can ingest and search logs cheaply, but you must operate storage and collectors and give up Axiom's managed serverless scaling and polished event-query experience.
setupThe easy single-node path still needs collectors and persistent storage; production HA adds Kubernetes, object storage, PostgreSQL, and NATS.

A searchable event store with traces and dashboards attached; ClickHouse does the lifting.
A fast log store and query UI; metrics and traces are somebody else's problem.
licenseApache-2.0
runsyour server
installDownload one server binary or run its Docker image; optional Compose demos add collectors and Grafana
dataLogs live in VictoriaLogs' on-disk partitions under `-storageDataPath` (default `victoria-logs-data`); cluster mode distributes the same format across storage nodes.
the catch vs AxiomIt is a fast log store, but it is narrower than Axiom's managed event platform and leaves dashboards, collection, alerting, and operations to other components.
setupYou must wire a log shipper and size disk/retention yourself, and dashboards or alerting normally mean adding Grafana and related components.

why people still pay for Axiom
People still pay for Axiom because monitoring must continue working during the exact outage it reports, which makes independent infrastructure and alert delivery the real product. The recurring cost buys probe geography, clocks, retries, deduplication, sampling, storage, paging, notification delivery, on-call rules, and its own uptime, not just the visible interface. If none of that applies to you, any pick above saves $300 a year.
