Mastra is a modern TypeScript framework designed specifically for agentic systems, enabling developers to build AI agents that use large language models and tools to solve complex tasks and reason about goals. It supports the full agent development lifecycle with features such as workflows, memory, workspaces, and observability. Mastra is used by companies like Brex, Marsh, and MongoDB to create various AI-powered applications, including conversational agents, domain-specific copilots, and workflow automations.
