Braintrust - 2026 Pricing, Features, Reviews & Alternatives

Braintrust is an active observability platform for teams building and operating AI agents and LLM-powered applications. It covers the full development lifecycle: instrumenting production agents with detailed tracing, running pre-ship evaluations against real datasets, surfacing patterns in live traffic through AI-powered clustering, and closing the loop between production signals and measurable quality improvements. Deployment options include managed SaaS, hybrid (BYOC), and self-hosted configurations available on the Enterprise tier, making it suitable for individual developers, growing teams, and large organizations with strict infrastructure requirements.

The platform unifies tracing, evaluation, dataset management, and production monitoring in a single workflow with no framework lock-in. Production traces convert directly into versioned regression test datasets, grounding evaluations in real failures rather than synthetic examples. The same scorer library runs identically in development experiments and live production, eliminating scoring inconsistency across environments. Quality gates in CI block merges that drop accuracy below defined thresholds. An AI agent called Loop runs evaluations, generates test cases, and iterates on prompts autonomously from plain-language descriptions. The Topics feature automatically clusters production logs into themes such as user intents, failure modes, and edge cases without requiring predefined categories. Additional capabilities include a prompt playground, MCP server for IDE-based log queries and eval runs, an AI Gateway with caching and provider fallbacks, and the Brainstore database, which returns trace queries across millions of spans in under a second.

Braintrust serves engineering and product teams across software, fintech, e-commerce, infrastructure, and developer platform verticals. SDKs are available for Python, TypeScript, Go, Ruby, C#, and more, with integrations for OpenTelemetry, LangChain, LangGraph, OpenAI Agents SDK, Vercel AI SDK, Google ADK, and others. Security and compliance coverage includes SOC 2 Type II certification, GDPR compliance, HIPAA compliance, SSO, and role-based access control (RBAC). Pricing is usage-based with no per-seat charges; a free tier includes 1 GB of processed data and 10,000 evaluation scores.
