v3.0, out now
Observability for systems that don't fit a dashboard.
Beacon traces, profiles and logs across distributed services without the storage bill of a hyperscaler.
Read the docs
Trusted across the industry
What you get
Drop-in OpenTelemetry
One env var, every language. Auto-instrumentation for HTTP, gRPC, queues and DBs.
Sampled, not sampled out
Tail-based sampling keeps the rare bad request and discards the noise, no surprises at 3am.
Cost you can predict
Per-host, not per-event. Storage tiers down to S3 after seven days, replayable on demand.
We cut observability spend 80% and stopped guessing at root cause.
