Braintrust
The AI observability platform for building quality AI products
Details
Braintrust is an AI observability platform designed to help teams build, monitor, and improve AI applications at scale. It provides a unified environment for tracing production behavior, evaluating outputs, and automating quality improvements. The platform is framework-agnostic and integrates with any AI stack, making it suitable for engineering and product teams alike. Braintrust emphasizes catching silent failures and regressions that are common in AI systems, offering tools to inspect traces, score outputs, and block bad releases before they reach production.
Key Features
- Real-time trace inspection for prompts, responses, and tool calls
- Eval system with LLM-based, code-based, or human scoring
- Automatic pattern discovery via Topics (task, issue, sentiment clustering)
- Continuous online scoring and quality gates to block bad releases
- Custom facets and annotation interfaces tailored to team workflows
- One-click conversion of production traces into eval datasets
- MCP server for querying logs, running evals, and updating prompts from an IDE
- Framework-agnostic integration with existing AI stacks
Use Cases
- Monitoring production AI applications for drift and regressions
- Running experiments to compare prompts and models side-by-side
- Building regression tests from real production failures
- Automating quality gates to prevent bad releases
- Collaborating across engineering and product teams on AI quality
- Optimizing evals and prompts with agent-assisted improvement (Loop)

Frequently Asked Questions
What types of AI models does Braintrust support?
Based on available information, Braintrust is framework-agnostic and appears to work with any AI stack, including LLMs and agents. Specific model support should be verified on the product's documentation.
Is there a free tier or trial available?
The homepage does not mention a free tier. Pricing is listed as 'contact sales,' so interested users should inquire directly about trial options.
Can Braintrust be used with non-LLM AI models?
The platform focuses on AI observability and mentions traces, prompts, and tool calls, which suggests it is designed for LLM-based applications. Support for other AI model types should be confirmed with the vendor.
How does Braintrust handle data privacy and security?
The homepage does not detail security or data privacy features. Users should review Braintrust's security documentation or contact sales for specifics.
Does Braintrust integrate with existing monitoring tools?
Braintrust is described as framework-agnostic and offers an MCP server for IDE integration. Specific integrations with other monitoring tools should be checked in the documentation.
What is the Loop agent AI feature?
Loop is described as an agent that helps improve AI by generating better prompts, scorers, and datasets automatically based on user-defined optimization goals. Details on its capabilities should be verified.
