Mastra

Mastra Factory is an open-source (Apache 2.0) TypeScript framework for building production-grade AI agents, paired with a managed cloud platform for deployment and scaling. It bridges the gap between rapid prototyping and real-world production systems by providing built-in memory, tool calling, multi-step reasoning, and a workflow engine for orchestrating complex AI pipelines.

Architecture & Technical Design

Mastra Factory uses a Configurable Agent architecture where developers define one or more agents, each bound to specific tools, memory rules, and reasoning chains. The system features a visual workflow engine that enables building complex AI pipelines with conditional nodes, loops, and parallel branches.

Performance & Observability

The tool includes a built-in Observability system that tracks every event, model call, and CPU time usage, providing full visibility into agent performance in production. It also supports native integration with vector databases for RAG (Retrieval-Augmented Generation) capabilities, allowing agents to access and cite specific knowledge.

Deployment & Scaling

Agents built with Mastra Factory can be deployed via Mastra Cloud (managed infrastructure) or self-hosted using open-source packages. The platform supports deployment on multiple platforms including Vercel, Cloudflare Workers, and traditional Node.js, with automatic horizontal scaling based on request volume.

Model Integration

The tool is model-agnostic, supporting multiple models from OpenAI, Anthropic, Google, Mistral, and others, giving developers flexibility to choose the best model for each task based on cost and performance. It also supports the MCP (Model Context Protocol) to extend agent capabilities with external tools.
