EvalView vs Braintrust

If you are comparing EvalView vs Braintrust, the core split is:

• Braintrust is strongest for broader eval workflows, production data loops, and scoring infrastructure.
• EvalView is strongest for regression testing with golden baselines and tool-path diffs.

Choose Braintrust when

• you want a broader evaluation platform
• you care about experiment/data/scorer workflows
• you already have production traces and want to turn them into evaluation loops

Choose EvalView when

• you need tool-calling agent testing
• you want golden baseline regression detection
• you want to go from zero tests to a draft suite from just an endpoint or log file
• you want a simpler CI-facing workflow:

evalview generate --agent http://localhost:8000
evalview snapshot tests/generated --approve-generated
evalview check tests/generated

Key distinction

Braintrust is closer to a broad eval platform. EvalView is closer to a focused regression testing runner for agents.

If your question is “Did my agent break?”, EvalView is the sharper fit.
