What is Braintrust?
Braintrust is a platform for evaluating, testing and monitoring AI applications, used by product teams to measure quality before and after each release. It combines experiments, datasets, prompt playgrounds and production logging in one tool.
Teams write evals in code or the UI, compare runs side by side, and gate deployments in CI when scores drop. Production traces feed back into datasets, and an AI assistant helps write scorers and analyze failures.
A free tier covers small projects, and the Pro plan adds more data and retention for teams. Enterprise customers can run a hybrid deployment that keeps data in their cloud.
