When to stay with Braintrust
Documented strengths from our Braintrust review — switching isn't always the right call:
- No per-seat pricing at any tier — users, projects, datasets, playgrounds, and experiments are unlimited even on the free Starter plan
- The free tier is genuinely usable for a small production app: 1 GB of processed data and 10k scores per month with no credit card required
- Overage rates get cheaper on Pro rather than more expensive, so scaling volume improves unit economics instead of penalising it
