Mastra Factory is a comprehensive open-source (Apache 2.0) development platform built by the Mastra team to enable developers to build and deploy AI agents and workflows in TypeScript. Officially launched in October 2024, the platform provides a complete framework combining long-term memory, customizable tools, MCP (Model Context Protocol) support, and production-grade observability. Its multi-model architecture allows seamless integration with major LLM providers including OpenAI, Anthropic, and Google Gemini, giving developers full flexibility in selecting the optimal engine for each task.
Architecture and Core Components
Mastra rests on four integrated technical pillars: First, the Agent Framework provides a ready-made structure for building autonomous agents capable of reasoning, remembering, and acting with custom tools. Second, the Workflow Engine enables orchestration of multi-step AI processes with full control flow and conditional logic. Third, RAG support (Retrieval-Augmented Generation) with document chunking and vector stores for building precise knowledge retrieval systems. Fourth, Mastra Cloud — a managed cloud platform for deploying and monitoring agents and workflows with detailed dashboards.
Performance and Observability Features
The platform offers advanced observability tracking execution events, CPU time, and data retention periods. The free tier starts with 100K observability events and 24 CPU hours with 15-day data retention, while the Teams plan scales to 1M events and 250 CPU hours with 6-month retention. Enterprise plans add SSO and SOC 2 documentation, making it suitable for companies requiring strict security compliance.
Integration and Deployment
Mastra projects can be deployed either self-hosted under the Apache 2.0 open license, or via managed Mastra Cloud. The platform provides a fully documented REST API for external system integration and supports deployment across Web, Mac, Windows, and Linux environments. This deployment flexibility makes it suitable for startups seeking rapid solutions and large enterprises requiring full infrastructure control.
