How Braintrust compares
Braintrust offers a competitive entry point with a $0/month Starter tier that includes unlimited users and projects, which is generous compared to some competitors who gate these behind per-seat pricing. Its Pro tier at $249/month targets small teams with a flat platform fee plus usage-based components, placing it in the mid-market of LLM observability tools like LangSmith and Langfuse. Enterprise pricing is custom, catering to high-volume or high-security needs similar to Arize or Aporia.
Alternatives by price
Who this fits
Ideal for individual developers and small teams (up to 5 people) looking for a scalable LLM evaluation and observability platform with a low entry cost and flexible usage-based growth.
Notes
- Processed data refers to data ingested when sent to Braintrust, not retained storage. Deleting data does not lower processed data totals for the month.
- Scores represent evaluation results generated by the platform or sent to it.
- Starter plan is limited to 1 human review score per project, while Pro and Enterprise are unlimited.
