Braintrust
Evaluation platform for scoring prompts, agents, and model changes before they ship.
AI product teams that change prompts or models often and will keep a scored dataset.
Teams that want a dashboard without writing evals, or buyers looking for a full observability suite.
Verdict
Braintrust is a good fit for product and engineering teams that need a scored gate on prompt and model changes before they ship. Pricing is mid-range for eval tooling and tracks how seriously you run datasets and scorers. Teams that staff the eval work speak well of it; it stands beside the app framework rather than replacing product judgment.

Review Excerpts
Below are excerpts from public reviews. Paid reviews and pay-for-play sites such as Clutch were excluded.
“We've been using Braintrust for evals at Zapier and it's been really great -- pumped to try out this proxy (which should be able to replace some custom code we've written internally for the same purpose!).”
“I've been using Braintrust at Coda and it's awesome - saved us so much time. Congrats on the launch!”
“I’ve been using Braintrust Proxy for this until now.”
“Braintrust: Interesting approach to evaluation but feels like an early-stage product. Documentation is sparse and integration options are limited.”
“Braintrust is really powerful for building AI apps. It's an all-in-one platform with evals tracking, observability, and playground tools for rapid experimentation. Very well-designed and built app that's also very fast to use.”

- Team habit fit
- Company & commercial
- Innovation &
- product leadership
- Project management &
- communication
- Pricing
- Contract fairness
Pricing measures whether the price looks fair for the value delivered, including packaging and renewal friction that show up in real buying cycles.
