Mastra Factory is a comprehensive open-source development platform for building AI agents and workflows in TypeScript. Launched by Mastra.ai, it provides a framework to move intelligent agents from prototype to production, offering memory, tools, MCP, and observability.
Architecture
The platform combines an open-source framework with a managed cloud platform. Developers define agents using simple APIs with full TypeScript support and static typing. Agents can execute multi-step tasks, call external tools, and access knowledge bases via built-in RAG.
Workflow Engine
The workflow engine enables building deterministic AI pipelines with branching and loops, allowing developers to create repeatable and testable processes, reducing LLM unpredictability.
Built-in RAG
Includes a built-in RAG system with vector store integrations and chunking utilities, enabling agents to access enterprise data and answer based on specific knowledge.
Model Routing
Supports intelligent model routing, allowing switching between providers like OpenAI, Anthropic, and Google. Developers can choose the best model per task based on cost, performance, or accuracy.
Observability & Evals
Provides observability, evals, and a local dev playground for testing and monitoring agents. Metrics include observability events, CPU time, and data retention.
Performance & Integration
Mastra Factory is designed to be lightweight and fast, with support for multiple deployment platforms. It integrates with modern DevOps tools and supports cloud or self-hosted deployment.
