The honest brief

Braintrust

Eval-first: prompts are versioned objects and CI scorers block a merge when quality regresses.

  • Eval workflow as the primary interface
  • CI scorers block merges on regression
  • Dataset versioning + OTel tracing
  • Generous free tier
  • Closed-source SaaS
  • Self-hosting needs Enterprise contract
  • Overkill for tiny single-file eval needs

Maxim AI

Simulates multi-turn agents across personas pre-release and tests any agent via its HTTP endpoint, no SDK rewrite.

  • Agent simulation across personas/scenarios
  • HTTP-endpoint testing, no code changes
  • Full lifecycle: experiment, eval, observe
  • Online and offline custom metrics
  • Newer, smaller community than rivals
  • Freemium; opaque enterprise pricing
  • Closed source
  • Crowded eval/observability space
