What's Good
Type-safe agent development in TypeScript. Define agents with proper types, compose them into workflows, run evals to measure quality. The framework approach means structure and reusability. Good fit for teams building agent systems rather than one-off scripts.
The Catch
Framework, not a coding CLI. Mastra helps you build agents; it is not an agent itself. Learning curve for the runtime concepts. You are committing to their abstractions.
Verdict
TypeScript agent framework for teams building agent systems.
