Mastra

What is Mastra?

Mastra is an open-source TypeScript framework designed for building AI agents and workflows. It provides developers with essential tools for creating intelligent applications, including built-in support for agent workflows, memory management, and real-time streaming capabilities. The framework is built for TypeScript developers who need a structured approach to AI agent development. It offers an interactive playground for testing and experimenting with agents, alongside evaluation tools for assessing agent performance. Mastra also includes tracing functionality, allowing developers to monitor and debug agent behavior throughout execution. Key features include workflow orchestration for managing complex agent processes, persistent memory systems for maintaining context, and streaming support for real-time interactions. The interactive playground enables rapid prototyping without requiring extensive setup, while the integrated evals system helps developers validate agent outputs and behavior. Available on npm as @mastra/core, the project is actively maintained on GitHub and benefits from community contributions. The framework targets developers building production-grade AI applications who want reliable tooling and clear visibility into agent operations. Mastra combines essential infrastructure components needed for agent development into a cohesive TypeScript-first ecosystem, eliminating the need to integrate multiple disparate tools.
