Continue to About ↓- What it does
- Braintrust is a cloud platform for observing, evaluating and improving LLM and agent applications.
More detail
- It traces every prompt, response and tool call in production, scores outputs with code, LLM judges or human review, and turns real traffic into versioned eval datasets and CI quality gates.
- An AI layer surfaces recurring production patterns and suggests fixes.
- Best for
- Engineering, ML and product teams running LLM agents or RAG assistants in production that need per-request traces, quality scoring and regression gates before release.
More detail
- Also fits teams wanting the same scorers to run in offline experiments and in live traffic.
- Pricing
- Subscription plus metered usage, no perpetual free tier.
More detail
- Starter: $0/month with $10 monthly model credits, 1 GB processed data, 10k scores and 14-day retention
- overages are +$4/GB processed data and $2.50 per 1,000 scores.
- Pro: $249/month with $100 model credits, 5 GB data, 50k scores and 30-day re
- Main limitation
- Teams without LLM or agent traffic, and very low-volume or hobby users, since the free Starter tier keeps only 14 days of data and caps included data and scores.
More detail
- Buyers needing self-serve on-prem or published custom data residency will find that Enterprise-only.

About
- Braintrust is a cloud platform for observing, evaluating and improving LLM and agent applications.
- It traces every prompt, response and tool call in production, scores outputs with code, LLM judges or human review, and turns real traffic into versioned eval datasets and CI quality gates.
- An AI layer surfaces recurring production patterns and suggests fixes.
What it helps with
- Agents fail opaquely in production, with no way to see why a specific request went wrong.
- Quality drifts or regresses silently after prompt or model changes.
- Prompt and model choices are made on subjective impressions rather than measured results.
- Test sets are synthetic and miss real failure modes seen in production.
- Too many production traces to read manually, so recurring issues go unnoticed.
- Bad changes reach production because there is no quality gate in CI/CD.
Capabilities
A practical view of what is available and where limitations apply.
| Offering | Available | Detail |
|---|---|---|
| Production tracing | Yes | Nested span traces of LLM calls, tool calls and retrieval steps with latency, tokens and cost per step, via SDK auto-instrumentation or gateway base URL. |
| Evaluation and scoring | Yes | Deterministic code scorers, LLM-as-judge and human review, with versioned datasets and side-by-side experiment diffs. |
| CI/CD quality gates | Yes | GitHub Actions gate that can block bad changes, plus remote evals triggered by code or production changes. |
| Automated pattern discovery | Yes | Patterns and Topics surface recurring issues and classify production traces; vendor-described capability, not independently benchmarked. |
| Monitoring dashboards and alerts | Yes | Track latency, cost, quality and volume, with threshold alerts on score drops, latency spikes and error rates. |
| Framework and SDK coverage | Yes | Python, TypeScript, Go, Ruby, C#, LangChain, OpenTelemetry and MCP; vendor claims no framework lock-in. |
| Compliance and access controls | Limited | SOC 2 Type II, GDPR, HIPAA, SSO/SAML, MFA and RBAC are stated; HIPAA BAA and uptime SLA are Enterprise-only. |
| Self-serve on-prem or custom data residency | No | On-prem or hosted deployment is Enterprise-only at custom pricing; self-serve region choices are unknown. |
| Published token rate card | Unknown | Pricing page says only 'then token rates' and points to a detailed pricing page not included in the evidence. |
| Independent performance validation | Unknown | Speed and database benchmark claims are first-party; no independent benchmark was found, and third-party review volume is thin. |
