Product comparison

Verdictan vs. LangChain LangSmith

You need to debug agents, measure quality and keep production policy enforceable.

Why Verdictan

Verdictan applies policy at the gateway and records request-level decision evidence for supported AI traffic. Run it in a self-hosted or air-gapped environment.

Key differences

Verdictan vs. LangChain LangSmith: Key differences

Monitoring and evaluation can detect a failure without owning the original gateway action.

  1. LangSmith records agent execution steps

    Traces contain runs for models, tools and application logic, with tags and metadata.

  2. Offline and online checks serve different goals

    Offline evaluations use datasets and references. Online evaluations score live runs and threads.

  3. Alerts cover cost, errors, latency and feedback

    LangSmith uses project thresholds for selected production metrics.

Common questions

What to ask before you decide

Can LangSmith ingest OpenTelemetry traces?

Yes. LangSmith documents OTLP tracing for compatible applications.

Does LangSmith support online evaluation?

Yes. Online evaluators score production runs and threads without reference outputs.

Can LangSmith alert on cost?

Yes. Project alerts can use total run cost over a selected time window.

Can LangSmith run in a customer cloud?

Yes. Self-hosting is an enterprise add-on that the customer operates.

Does an online evaluation block the original request?

The reviewed sources describe production scoring and automation. They do not establish a general inline gateway block.

What should we test first?

Trace one agent failure, score it online, add it to a dataset and verify the fixed gateway outcome.

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 feature. It does not mean the feature is absent.
  • Confirm the LangSmith plan for self-hosting, alerts, retention and evaluator execution.
  • Measure rule and evaluator delay before designing an operational response.
  • Keep gateway enforcement separate from trace scoring unless the application connects them explicitly.
