Ship quality AI at scale

Turn production traces into evals, compare prompts and models, and improve quality with every release.

Trusted by the best AI teams

Inspect traces in real time

AI fails differently than normal software. You need a new kind of observability to monitor and fix it.

AI drifts, hallucinates, and regresses silently. The best teams observe production, evaluate against expectations, and iterate continuously.

Scalable log ingestion
Trace everything
Inspect prompts, responses, and tool calls in real time
Live performance monitoring
Measure quality with evals
Score outputs with LLMs, code, or humans
Automations and alerts
Catch issues early
Block bad releases before they hit production

AI observability and evaluation for the whole team. From engineering to product, in one platform.

Observability

See what actually happened in production. Inspect every trace, drill into tool calls, and track latency, cost, and quality in real-time. Get alerts before your users notice something's wrong.

Evals

Define what good looks like before you ship. Run experiments against real datasets, compare prompts side-by-side, and catch regressions automatically in CI. Score with LLMs, code, or humans to keep quality moving in the right direction.

Everything you need to build smarter, faster

Loop agent
AI that helps you improve AI. Describe what you want to optimize, and Loop generates better prompts, scorers, and datasets automatically.
Optimize your evals
Customizable trace views
Build annotation interfaces that match your task. Review support conversations differently than code generation, with no frontend work required.
Build custom views
Trace to dataset
Turn production traces into eval datasets with one click. Build regression tests from real failures and edge cases, not synthetic examples.
Explore datasets
MCP
Query logs, run evals, and update prompts directly from your IDE. Braintrust's MCP server connects your coding agent to your AI stack.
Set up MCP
Framework agnostic
Framework agnostic
Works with any stack you're already using. No framework lock-in, no rewrites, no vendor dependencies to manage.

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

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

Malte Ubl, CTO

We didn't realize we needed deep observability until Braintrust.

Sarah Sachs, AI Lead

There are some problems we wouldn't know were problems without Braintrust.

Josh Clemm, VP of Engineering

We can run hundreds to thousands of experiments with Braintrust.

Luis Héctor Chávez, CTO

Braintrust helped us identify several patterns that we wouldn't have found.

Sarav Bhatia, Sr. Dir. of Engineering

Braintrust is the core of our evaluation framework process.
