Description

Mastra is an open-source AI agent development framework built with TypeScript that helps developers create, test, deploy, and maintain intelligent applications. The framework provides configurable AI agents capable of reasoning through tasks, interacting with external tools, accessing information, and executing multistep operations. Its workflow orchestration capabilities allow developers to define structured sequences with conditional logic, parallel execution, retries, error handling, and human-in-the-loop approvals. Mastra includes persistent memory functionality that enables agents to retain conversation history, maintain structured working memory, and retrieve relevant information from previous interactions. Its agent harness supports long-running tasks, shared execution state, multiple operating modes, and persistent storage for complex autonomous applications. Developers can integrate different large language models through a unified model router and connect agents to external applications using APIs and Model Context Protocol servers. Built-in observability features provide execution traces, logs, performance metrics, token usage tracking, and debugging information for monitoring agent behavior. Evaluation tools support automated scoring, reusable test datasets, experiments, and performance comparisons to improve agent reliability before production deployment. Mastra integrates with frameworks such as React, Next.js, and Node.js and supports deployment through Mastra Cloud, standalone servers, and compatible cloud infrastructure.
