Free alternatives to Braintrust
1 free program that can replace Braintrust, a pairing checked by Radar's AI reviewer or by Radar.
Braintrust is a hosted platform for teams that build software on top of language models. It is used to record what an AI application does, run tests that score its answers and compare changes before they reach users. Developers and product teams working on AI features are its typical users.
Before switching, check:
- How much of your code is tied to its libraries, since the logging and test calls will need to be rewritten for another tool.
- Whether you can export your logs, test sets and past results, and in which format.
- How the team will review results together: a hosted service gives teammates a shared interface, while a tool you run yourself needs hosting and upkeep.
- Privacy: prompts and answers often contain customer data, so think about where they will be stored.
