Key differences

Verdictan vs. W&B Weave: Key differences

Passive monitoring can detect a risk after the application has already processed the call.

  1. Weave records calls, traces and threads

    The trace tree shows hierarchy, latency, tokens, cost and captured inputs and outputs.

  2. Evaluations connect datasets, models and scorers

    Teams can run repeatable comparisons and store scorer results with calls.

  3. Monitors and guardrails have different effects

    Monitors score passively. Guardrails run inline and can block or modify application calls.

Common questions

What to ask before you decide

Can Weave ingest OpenTelemetry traces?

Yes. Weave documents OpenTelemetry trace ingestion.

Does Weave support production scoring?

Yes. Monitors sample calls, and teams can also apply scorers asynchronously.

Can Weave block a call?

Yes. An inline guardrail can block or modify an application call.

Do Weave guardrails require code changes?

Yes. The application must add the guardrail to its execution path.

Can W&B run in a customer environment?

Yes. W&B documents a self-managed deployment option.

What should we test first?

Compare one passive monitor result with one inline guardrail and the related gateway record.

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 not-documented status means the reviewed sources did not establish the capability. It does not mean the feature is absent.
  • Confirm the W&B deployment, plan, region and data-retention terms.
  • Measure passive monitor delay and inline guardrail latency with representative calls.
  • Confirm SDK feature parity for each application language before rollout.
