Key differences

Verdictan vs. Comet Opik: Key differences

Near-real-time scoring can detect a failure after the original request has completed.

  1. Opik records traces, spans and threads

    Trace views include model cost and support OpenTelemetry data.

  2. Test suites combine datasets and metrics

    Teams can run repeatable evaluations and score production traces near real time.

  3. Blocking checks stop the application path

    A failed validation raises an exception for application code and stores the result in the trace.

Common questions

What to ask before you decide

Is Opik open source?

Yes. Comet documents Opik as an open-source platform with managed and self-hosted options.

Can Opik receive OpenTelemetry traces?

Yes. Opik documents OpenTelemetry ingestion.

Does Opik score production traces?

Yes. Online evaluation rules score selected traces near real time.

Can Opik block an application call?

Yes. Failed guardrail validation raises an exception for application code to handle.

Does self-hosted Opik include user management?

No. The self-hosting guide states that user management is not included.

What should we test first?

Trace one failure, score it online and verify both inline control records.

How we researched this page

We checked the official sources below on Aug. 11, 2026. Product scope, plan access, beta status and support can change.

  • This review covers the listed public sources on Aug. 11, 2026.
  • Confirm the plan, region, version and contract terms before a production decision.
  • A verify status means the reviewed sources did not establish the point. It does not mean the feature is absent.
  • Confirm the Opik release, deployment, storage, retention and access-control design.
  • Measure online evaluation delay with representative production volume.
  • Test application exception handling and fail-closed behavior before enabling blocking guardrails.
