TypeScript AI framework — agents, workflows, RAG, and integrations for JS/TS developers.
Unique: Provides a structured evaluation framework with custom scorers and versioned datasets, enabling systematic agent quality measurement and A/B testing without external evaluation platforms. Scorers are composable and can measure multiple dimensions.
vs others: More integrated than running manual tests — Mastra's evaluation system is built into the framework with dataset versioning, scorer composition, and experiment comparison, vs writing custom evaluation scripts
