OpenObserve

What is OpenObserve?

Observability platform for logs, metrics, traces and session replay, stored as Parquet on S3.

Who is OpenObserve best for?

OpenObserve is best for SRE teams that want to self-host logs, metrics and traces on low-cost S3 storage.

• Replacing Elasticsearch for logs

  Columnar Parquet storage on object storage keeps large log volumes cheap, and logs are searched with SQL or full text.

• All signals in one tool

  Logs, metrics, traces, dashboards, alerts and pipelines share one UI, with metrics queried in SQL or PromQL.

• Frontend monitoring

  Real user monitoring, session replay and error tracking sit next to backend traces in the same open source build.

How much does OpenObserve cost?

OpenObserve's open source edition is free to self-host, and OpenObserve Cloud charges $0.70 per GB ingested plus $0.01 per GB queried, with no per-user fees.

A 12-month Cloud contract lowers ingestion to $0.50 per GB. Extra retention for logs, traces and other non-metrics data costs $0.02 per GB per 30 days. Enterprise, at a custom price, adds bring-your-own-bucket retention and SLAs, and Self-Hosted Professional above 50 GB a day is priced by sales. Full pricing on openobserve.ai.
