Verdict
Braintrust takes the top spot because prompt versions, evals, datasets and production traces live in one system, and code can pin a prompt by version or environment.
What customers praise
Versioned prompts can be pinned by version or environment in code, next to evals, versioned datasets and tracing; its site names Notion, Replit and Cloudflare as customers.
What customers criticise
The lowest paid plan is $249 a month plus usage, a big step from the free Starter tier.
Best for
AI product teams that want prompt versioning tied to evals and production tracing in one platform.
