Our verdict on Braintrust
Braintrust is a platform for evaluating, monitoring, and improving AI applications and agents. It suits teams that need evaluation workflows alongside production observability, including dataset management, experiment comparison, scoring, prompt versioning, and quality gates. Its feature set covers offline and online evaluations, LLM-as-a-judge scoring, custom scorers, human review, production tracing, and conversion of production traces into evaluation datasets. Hosted, API, and self-hosted options support different deployment needs.
Pricing separates a usable free tier from paid controls and higher included usage. The Starter plan costs $0 per month and includes unlimited users, projects, datasets, playgrounds, and experiments, with 14-day retention. The Pro plan costs $249 per month and adds custom charts, environments, priority support, and RBAC, along with 30-day retention. Enterprise uses custom pricing and adds custom data retention and export, premium support, RBAC, and on-prem or hosted deployment. Usage allowances and additional charges vary by plan, so teams should compare expected processed data and score volume with the included amounts.
The platform fits teams that want one workflow from development evaluation to production monitoring and CI/CD regression gates. Integrations include OpenAI, Anthropic, Google, Mistral, Azure, Meta, OpenTelemetry, LangChain, CrewAI, Vercel AI SDK, LlamaIndex, and Mastra. Self-hosted data-plane deployment is relevant for organizations with stricter data-control requirements. Teams seeking a narrowly focused evaluation tool, or those unwilling to commit to the Pro starting price for advanced controls, may prefer a simpler alternative. Braintrust is the stronger choice when trace data, evaluation datasets, prompt rollback, and release gates need to work together.
