What Braintrust does
Braintrust logs production traces from LLM applications and agents and runs scored evaluations of their outputs against datasets. Prompts, scorers, experiments, and human review of logged data sit in the same interface.
Why teams reach for it: Ties production traces to scored evaluations, so agent changes are measured in CI before shipping.
