Mastra

Mastra Factory is a comprehensive open-source platform for building and deploying AI agents in TypeScript. Developed by Mastra, a US-based company, and launched in late 2024, it serves as an advanced framework bridging the gap between rapid prototyping and scalable production systems. The platform combines a powerful workflow engine, built-in memory, and full RAG (Retrieval-Augmented Generation) support, enabling developers to create agents that reason, remember, and act autonomously.

Architecture & Core Components

Mastra Factory consists of several integrated architectural layers. The first is the Agent Framework, supporting tool calling, structured output, and multi-step reasoning. The second is the Workflow Engine, allowing step chaining, branching, and human-in-the-loop approvals. The third is the Memory & RAG system with multiple vector store integrations (Pinecone, Weaviate, Chroma). Finally, the Model Routing layer provides a unified API to switch between OpenAI, Anthropic, Google, and others without code changes.

Performance & Operational Features

The platform offers a local dev server with an interactive Playground UI for instant agent testing. It also provides Mastra Cloud for deployment and observability, tracking events, CPU time, and data retention. Self-hosting is supported under the Apache 2.0 license, giving teams full infrastructure control.

Integrations & Use Cases

Mastra Factory integrates with the MCP (Model Context Protocol), expanding agent capabilities to interact with external tools. It supports web and API deployments, running on macOS, Windows, and Linux. With TypeScript support, it targets web developers and engineering teams building production AI applications.
