Should I Use OpenObserve?
High-performance, unified observability for the AI era. 140x lower storage cost.
Depends
DependsBuy if you ingest heavy log volume, have DevOps capacity to self-host or patch, and want Datadog-level features at a fraction of the cost.
Cheap, capable Datadog alternative for teams with ops muscle; open-core caveats and fresh CVEs.
