OpenObserve

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.

- webself-hosteddocker to self-host

- Hosted signup, or a single binary/Docker container; Helm plus external services for HA
- setup
- The easy single-node path still needs collectors and persistent storage; production HA adds Kubernetes, object storage, PostgreSQL, and NATS.

- Telemetry is stored as Apache Parquet on local disk or object storage; single-node metadata defaults to SQLite, while HA uses PostgreSQL and NATS.

VictoriaLogs
open sourceApache-2.0Self-host2.1kaug 2026A fast log store and query UI; metrics and traces are somebody else's problem.
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.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Download one server binary or run its Docker image; optional Compose demos add collectors and Grafana
- setup
- You must wire a log shipper and size disk/retention yourself, and dashboards or alerting normally mean adding Grafana and related components.
- your data
- Logs live in VictoriaLogs' on-disk partitions under `-storageDataPath` (default `victoria-logs-data`); cluster mode distributes the same format across storage nodes.

The hard boundary is high-performance cloud storage, query engine, integrations, and managed operations, plus independent infrastructure and reliable alerting.
