What is Braintrust?
Braintrust helps AI product teams evaluate and observe agents: they run experiments against datasets before release, monitor traces in production and turn failures into new test cases.
The platform is organized around observe, evaluate and discover. It ingests agent traces with prompts, responses and tool calls, runs experiments and side-by-side comparisons scored by LLMs, code or human reviewers, and analyzes production behavior with natural language queries and topic classification. Loop is an AI assistant that proposes better prompts, scorers and datasets. Traces can be converted into regression datasets, and an MCP integration exposes logs and evals in the IDE. Braintrust states SOC 2 Type II, GDPR and HIPAA compliance and offers hybrid deployment.
Braintrust AI features and use cases
- Scores experiments before releaseExperiments run a prompt or model against a dataset and score results with LLM, code or human scorers. Teams compare versions side by side and ship the better one.
- Improves prompts and scorers with LoopLoop analyzes results and generates improved prompts, scorers and datasets. Developers iterate faster on evaluation setups that would otherwise be written by hand.
- Turns production failures into testsPattern automations find recurring issues in traces, and failing traces become regression datasets. Problems seen in production are checked in every later release.
What sets Braintrust apart
- Free Starter plan with unlimited users, projects and experiments.
- Hybrid deployment keeps data in your own environment on Enterprise.
