Braintrust

Agent observability and evals for the whole team. From engineering to product, in one platform.

Observability

See what actually happened in production. Inspect every agent trace and tool call, search across millions of logs, and track latency, cost, and quality in real time.

Evals

Define what good looks like before you ship. Run experiments against real datasets, compare prompts and models side-by-side, and score outputs with LLMs, code, or humans.

Discovery

Turn production signals into improvements automatically. Topics surfaces patterns in real time across task, issues, and sentiment, online scoring catches regressions, and quality gates block bad releases.

Brainstore, the database built for AI data at scale. Designed for complex agent traces.

Agent traces are large and nested. Traditional databases can't handle the complexity. Brainstore is designed specifically for agent observability so you can query millions of traces quickly.
