Mastra

Mastra Factory is a comprehensive open-source platform for building and deploying AI agents and generative workflows using TypeScript. Developed by Mastra, a US-based company, its commercial version launched in October 2024. The platform bridges the gap between rapid prototyping and production by providing a full framework that includes memory, tools, Model Context Protocol (MCP), and observability.

Architecture

Mastra Factory employs a multi-layered architecture: a Model Layer that supports dynamic routing across multiple LLM providers such as OpenAI, Anthropic, and Google Gemini; an Agent Layer that enables building agents capable of multi-step reasoning and tool calling; a Workflow Layer that provides a deterministic execution engine supporting branching and loops; and an integrated RAG layer that includes document chunking, embedding, and vector store integrations. The platform also offers an Observability & Evals layer with a local development Playground for testing and debugging agents.

Performance Features

The platform features low latency thanks to local workflow execution and can process millions of events through its observability system. The workflow engine supports parallel and sequential execution with resumability from failure points. It also provides seamless integration with common DevOps tools like Docker and Kubernetes, facilitating production deployment. On the security front, the Enterprise plan supports RBAC, audit logs, and SOC 2 reports.

Core Use Cases

Mastra Factory targets developers and engineering teams building complex generative AI applications that require fine-grained control over workflows, long-term memory, and external tool-calling capabilities. It is particularly suited for building customer service agents, sales automation, document RAG systems, and intelligent coding assistants.
