The different angle DUBSAR is taking
DUBSAR is designed to make a deterministic decision before connected egress or a sensitive action, then expose the policy, human review and limitations to responsible people.
- AI-use discovery before rollout
- Deterministic policy separated from agents
- Human review for defined sensitive cases
- Evidence and coverage limits in the Cockpit

How to choose without relying on a logo grid
Use LangSmith when application development and evaluation are central. Evaluate DUBSAR when policy enforcement and accountable business decisions are central. Some teams may use both with carefully minimised data and distinct responsibilities.
Verify current documentation, deployment region, data handling, pricing and the exact flow you need before making a decision.

Frequently asked questions
What to know before going further.
Does DUBSAR replace LangSmith feature for feature?
No. This page explains overlap and differences. DUBSAR remains in private testing and should be evaluated on a bounded real flow.
Can the products be used together?
Potentially, but only with a clear traffic path, data boundary and division of responsibility. An integration must be tested rather than assumed.
