Deep Dive: Switching from Axiom to OpenObserve
Trade-offs, installation & data architecture
What you trade away
It 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.
How to deploy OpenObserve
Hosted signup, or a single binary/Docker container; Helm plus external services for HA
What it takes to run
The easy single-node path still needs collectors and persistent storage; production HA adds Kubernetes, object storage, PostgreSQL, and NATS.
Where your data lives
Telemetry is stored as Apache Parquet on local disk or object storage; single-node metadata defaults to SQLite, while HA uses PostgreSQL and NATS.
Why fork OpenObserve instead of vibe-coding a Axiom clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Axiom, ingest bounded logs, search them, and retain a compact local event store. The hard boundary is high-performance cloud storage, query engine, integrations, and managed operations, plus independent infrastructure and reliable alerting.
