TL;DR

OpenObserve is an AGPL-3.0 observability platform for logs, metrics, traces, dashboards, and alerts. It replaces Datadog or New Relic for teams that want to cut telemetry storage cost and run an open source observability stack on their own infrastructure.

who it's for

Who OpenObserve is for#

SRE teams reducing log storage costs

Use OpenObserve to retain more telemetry in object storage while keeping search, dashboards, and alerting available.

Skip if:

Skip if your team depends heavily on Datadog-specific integrations and managed workflows.

Startups consolidating observability tools

Logs, metrics, and traces in one open source platform can replace a patchwork of tools early in the infrastructure lifecycle.

Skip if:

Skip if no one on the team can operate an observability backend reliably.

the problem

The problem it solves#

Observability data grows faster than most infrastructure budgets. Logs, traces, metrics, and session data can create unpredictable bills in proprietary platforms, and teams often reduce retention or sampling just to control spend.

The operational risk is clear: when an incident happens, the missing data is often the data the team dropped to save money. Teams need observability they can afford to retain and query without giving all telemetry to a vendor.

how OpenObserve solves it

How it solves it#

Unified telemetry platform

Ingests logs, metrics, and traces into one observability interface with dashboards, search, and alerts.

Object-storage based architecture

Uses object storage for telemetry data, which can lower retention cost compared with vendor-priced hot storage.

Self-hosted and cloud options

Teams can run OpenObserve themselves or use the managed service depending on their operations capacity.

strengths · trade-offs

Strengths and trade-offs#

Strengths

  • Cost control for high-volume logsThe architecture is attractive for teams whose proprietary observability bill is driven by log volume and retention.
  • Open source observability stackAGPL-3.0 source availability gives teams a path to inspect and modify the platform instead of treating observability as a black box.

Trade-offs

  • -Datadog ecosystem is broaderOpenObserve covers core observability needs, but Datadog still has a larger integration catalog, mature enterprise workflows, and many specialized monitoring products.
versus alternatives

OpenObserve vs alternatives#

OpenObserve vs Datadog

OpenObserve and Datadog both help teams search telemetry, build dashboards, and alert on system behavior. OpenObserve focuses on open source self-hosting and object-storage cost control; Datadog focuses on a broad managed observability suite.

OpenObserve is better when telemetry volume and retention cost are the main pain. Datadog is still better when a team wants the richest managed integration catalog and can accept vendor pricing.

FAQ#

Is OpenObserve open source?

Yes. OpenObserve is open source under the AGPL-3.0 license.

What data can OpenObserve handle?

OpenObserve handles common observability data including logs, metrics, traces, dashboards, and alerts.

How does OpenObserve compare to Datadog?

OpenObserve gives teams an open source, self-hostable observability platform with a cost-control focus. Datadog remains stronger for managed enterprise features and its integration ecosystem.
