Braintrust
Braintrust traces language model calls end‑to‑end (prompts, responses, tool calls, latency, tokens, cost), offers SDKs, a gateway, dashboards for automated scoring and discovery, and a built‑in agent (Loop) to convert production failures into test datasets and eval suites.
Three documented plans: Starter ($0 / month), Pro ($249 / month), and Enterprise (custom pricing). Starter and Pro include model credits, processed data, scores, and retention tiers with overage rates documented.Is Braintrust right for you?
Good for
- Engineering or ops teams running language model‑powered agents who need end‑to‑end tracing, automated scoring, and dashboards to monitor latency, cost, and quality in production.
- Captures full nested traces including prompts, responses, tool calls, latency, tokens, and cost for every request.
- Built-in evaluation pipeline that can score outputs with language models, code, or humans and run automated scoring on production traffic.
Keep in mind
- Enterprise pricing, SLA, and agreement specifics are not published and require contacting sales.
- Some advanced features and retention policies are labeled as custom or omitted for lower tiers (for example S3 export and custom policies).
- If you require published enterprise SLA/BAA pricing or exact retention export terms without sales contact, confirm those items with Braintrust before purchase.
Pricing and plan limits
The pricing page lists monthly prices and included quotas with explicit overage rates and mentions custom Enterprise pricing; detailed enterprise fees and SLA/BAA pricing require contact.
