The full AI development loop in one platform

Instrument once. Iterate fast. Deploy with confidence. See your first traces in minutes.

1
from braintrust import traced

@traced
async def my_agent(query):
  prompt = braintrust.invoke(
    "support-prompt",
    input={"query": query},
  )
  return await llm(prompt)
Instrument and log
Wrap your AI calls in one decorator. Every prompt, model call, and tool use is logged automatically. Your production behavior is always visible.
2
Eval(
  "Customer support",
  data=golden_dataset,
  task=my_agent,
  scores=[
    Factuality,
    Coherence,
  ],
)
Eval, compare, and iterate
Run experiments against your dataset. Compare prompts, models, and parameters side by side. Know what actually improved before you touch production.
3
- name: LLM eval gate
  uses: braintrustdata/eval-action@v1
  with:
    api_key: ${{ secrets.BRAINTRUST_API_KEY }}
    fail_on_regression: true
Deploy and gate releases
Push prompts to production from the UI without a code deploy. Gate code releases in CI. Monitor live quality after every change.

Works how your team works

Engineers instrument in code and run evals in CI. Others can iterate on prompts in the UI. Everyone sees the same experiments, the same scores, and the same production data.

For engineers

from braintrust import traced
import braintrust

@traced
async def my_agent(query):
  # Pull versioned prompt from UI
  prompt = braintrust.invoke(
    "support-prompt",
    input={"query": query},
  )
  return await llm(prompt)

Instrument once with one decorator. Pull versioned prompts from the UI at runtime. No redeploy needed when wording needs to be tweaked.

For PMs & domain experts

Braintrust playground comparing Claude, GPT-5, and Gemini side by side

Compare any two experiments side by side. See exactly what improved, what regressed, and what it costs before anything touches production.

Built for LLMops from the start

Prompt management and versioning

Every prompt change creates a new version. Deploy to production from the UI without a code deploy. Roll back instantly if quality drops. No more prompt strings buried in git.

Experiment tracking across models and providers

Compare different models in one experiment. Track every run with full reproducibility with prompt version, model, dataset, and scores all recorded automatically.

One platform for tracing, evals, and CI/CD gates

Tracing, evals, prompt management, datasets, CI/CD gates, and production monitoring all connected in one workflow. No integrations to maintain and no data syncing between tools.

What our customers say

“Braintrust helps us ship AI agents customers actually trust.”
