## At a glance

| Dimension | Vellum | Braintrust |
|---|---|---|
| Primary persona | PM + engineer + cross-team | Engineer + ML |
| Prompt UI | **Visual builder** ✓ | Code + UI |
| Dataset / golden set workflow | Yes | **First-class — dataset is the unit** ✓ |
| Eval scorers | LLM judge + custom | **LLM judge + custom + custom code** ✓ |
| Experiment runs | Yes | **Best-in-class diff + A/B** ✓ |
| Deployment / versioning | **Yes — deploy prompts as endpoints** ✓ | Versioning + APIs |
| BYO LLM | Yes | Yes |
| Self-host | Enterprise tier | **BYO Cloud + self-host** ✓ |
| Pricing | Per-seat + usage | **Free tier + usage** ✓ |
| Best for | Cross-team prompt workflows, non-engineer-friendly | Engineer eval pipelines, dataset-first, Anthropic-credible |

## Verdict

Vellum is the right pick for cross-team prompt workflows where PMs / domain experts edit prompts + engineers deploy them — visual builder + deployment management is lower-friction for non-engineers. Braintrust is the right pick for engineer-led eval pipelines — dataset-first model, experiment diffs, used by Anthropic internally. Many teams use both: Vellum for cross-team authoring, Braintrust for the eval gate in CI.

## When to pick which

- **Vellum** — Cross-team prompt workflows, non-engineer-friendly visual builder, deployment management.
- **Braintrust** — Engineer eval pipelines, dataset-first, experiment diffs, Anthropic-credible.

## FAQ

### Cross-team prompt authoring?

Vellum — visual builder is non-engineer-friendly.

### Dataset-first evals?

Braintrust — dataset is the core unit.

### Self-host?

Both — Braintrust has BYO Cloud, Vellum enterprise tier.
