Mastra

aid: mastra-ai
name: Mastra
description: Mastra is a TypeScript framework for building AI-powered applications and agents, built by the team
  behind Gatsby (Sam Bhagwat, Abhi Aiyer, Shane Thomas). The framework provides production-grade primitives for
  agents, workflows, RAG, tools, memory, evals, voice, and observability, and integrates with 40+ model providers
  through the Vercel AI SDK. The framework is Apache 2.0 licensed open source, with a hosted commercial offering
  (Mastra Cloud) for deployment, tracing, and team collaboration, and an enterprise self-hosted edition for
  regulated environments.

  name: Mastra Framework
  description: The Mastra framework is a TypeScript-first agentic stack distributed as the @mastra/* family of npm
    packages. The core package wires agents, workflows, memory, RAG, tools, MCP, evals, voice, and observability
    into a single Mastra instance that can be embedded in Next.js, Express, Hono, SvelteKit, Astro, Nest, Fastify,
    Koa, or stood up as a standalone server. Models are reached through the Vercel AI SDK so any of 40+ providers
    (OpenAI, Anthropic, Google, Bedrock, Groq, etc.) plug in through one interface. Apache 2.0 licensed.

  description: Mastra agents define behavior with a model, instructions, tools, memory, and processors, then expose
    .generate() and .stream() for typed text, object, and structured output generation. Agents support multi-step
    tool calls, dynamic instructions, runtime context, scoped memory, and Vercel AI SDK v5 message format.

  description: Workflows are durable, graph-based pipelines composed from typed steps with branching, parallelism,
    loops, suspension, human-in-the-loop, and event triggers. Step inputs and outputs are validated against Zod
    schemas and each run is persisted so workflows can be replayed, resumed, and observed.
