Mastra

Mastra is a comprehensive TypeScript agent framework for prototyping and productionizing AI features within a modern JavaScript stack. Developed by the team behind Gatsby, it provides a robust set of tools to build sophisticated AI applications.

Key components include:

• Agents: Construct intelligent agents with persistent memory, tool-calling capabilities, and a unified API for switching between LLM providers.
• Workflows: Define complex, multi-step processes using durable, graph-based state machines. These workflows support branching, pausing, resuming, and real-time state tracking.
• RAG: Equip your agents with relevant context. Sync data from various sources, create knowledge bases, and perform advanced retrieval with a unified vector store API.
• Ops: Monitor and debug your applications with built-in tracing, performance metrics, and evaluation tools to ensure accuracy and efficiency.
