Braintrust

Your team deserves more from your agent observability platform - a single, connected place for instrumentation, investigation, and measurement, enhanced with intelligence.

In Braintrust, you can start with an open-ended prompt about agent behavior and carry the investigation into code, evals, automation, and monitoring.

New tools like Patterns and Debugger make it easier to find recurring behavior, get to root causes, and act on what you learn. The context you build in one step automatically follows to the next. Work in the platform with an enhanced Loop experience, or move to your coding agent of choice.

Even if you write good evals, there are always edge cases.

Users might try to solve a coding problem with an agent for tracking a pizza delivery.

Trace your MCP server in Braintrust to see what agents request, what your tools return, and the use cases emerging from those interactions.

Add intent and feedback to your traces so agents can explain what they’re trying to do and report problems they encounter. Patterns will surface repeated behaviors, and you can use Loop for open-ended investigations.

What is an eval?

A way to answer a question about your system.

A Trace Lake keeps your agents' execution history searchable and queryable, so you can investigate agent behavior and use what you find in evals.

Fast ingest and fast SQL. Cheap and scalable storage that can stay in your cloud. And the ability to find patterns in your agent traces.
