Overview
Braintrust is an observability platform for AI agents. It helps teams inspect prompts, responses, and tool calls in real time, track latency and cost, search across logs, and monitor production behavior as agents run.
It also supports evals for testing what ships. Teams can compare prompts and models side by side, score outputs with LLMs, code, or humans, and turn production traces into regression datasets. The platform includes task-specific trace views, custom annotation workflows, and pattern discovery across production traces.
Braintrust includes native SDKs for Python, TypeScript, Go, Ruby, C#, and more. It also has an MCP server for querying logs, running evals, and updating prompts from an IDE, plus security features like SSO/SAML, RBAC, SOC 2 Type II, GDPR, and HIPAA support.
