What Braintrust is
Braintrust is an observability platform for teams improving AI agents that run in production. It lets users inspect agent traces and tool calls while tracking latency, cost, and quality in real time. Teams can evaluate datasets, compare prompts and models, and score outputs with LLMs, code, or human reviewers. Discovery tools help find patterns in production traces, and the Loop agent can run evaluations, generate test cases, and iterate on prompts autonomously. Braintrust describes the platform as framework agnostic and lists native SDKs for Python, TypeScript, Go, Ruby, C#, and more. Its MCP server lets coding agents query logs, run evaluations, and update prompts from an IDE. Braintrust states that it is SOC 2 Type II certified and GDPR and HIPAA compliant, and offers SSO, RBAC, and hybrid deployment options. The free Starter plan includes 1 GB of processed data, 10,000 scores, and 14-day retention. Pro costs $249.00 per month, with additional charges beyond some usage limits.
