Mastra

Mastra Factory is the managed cloud platform launched in October 2025 by Mastra, the team behind the popular open-source TypeScript AI agent framework. It provides an end-to-end solution for building, deploying, and observing AI agents written in TypeScript. The platform follows a hybrid architecture: the open-source framework runs locally or on the user's infrastructure, while Mastra Cloud adds deployment, monitoring, and scaling capabilities. It is designed for developers and engineering teams that need to move from prototype to production without rebuilding their infrastructure.

Architecture and Core Components

Mastra Factory consists of three main layers. The first is the Agent Framework, which supports tool calling, long-term memory, and multi-step reasoning, allowing agents to retain conversation context and invoke external APIs. The second is the Workflow Engine, which provides deterministic graph-based orchestration of AI steps, ensuring repeatability and traceability. The third is the Observability & Ops layer, which tracks observability events, consumes CPU time, and retains data according to the selected plan.

Model Routing

The platform offers a unified API to route requests across different model providers such as OpenAI, Anthropic, and Google, enabling model switching without code changes. This is critical for companies optimizing cost, performance, or compliance per use case.

RAG and Evals

Mastra Factory includes built-in Retrieval-Augmented Generation (RAG) support with evaluation tools (Evals) to measure output quality, plus a local dev playground for testing agents before deployment. It also supports the Model Context Protocol (MCP) to extend agent capabilities via external tools.

Performance and Scaling

The platform uses a scalable cloud architecture with clear plan limits: the free Starter plan provides 100K observability events and 24 CPU hours per month, while the Teams plan provides 1M events and 250 CPU hours. Overage is billed on a tiered basis (e.g., $10 per additional 100K events on the free plan).

Integration and Security

The Teams plan supports enterprise features such as SSO and SOC 2 documentation, while the Enterprise plan adds RBAC, audit logs, and uptime SLAs. These features make the platform suitable for regulated environments requiring strict compliance.

In short, Mastra Factory is not just an agent-building tool but a full AI Agent Ops platform covering the entire agent lifecycle from local development to cloud deployment and continuous monitoring, with a strong focus on TypeScript as the first-class language for developers.
