Mastra Factory
Open-source tool that takes GitHub or Linear issues through triage, planning, building and pull request review with coding agents.
Overview
Mastra Factory is an open-source tool built on Mastra’s TypeScript agent framework. It takes GitHub or Linear issues through triage, planning, building and pull request review using coding agents, while people answer questions, approve plans and merge the result.
Agents run in sandboxes, on Mastra’s cloud by default or on your own server or E2B, and you connect your own model provider. Agents and tools can be changed in code, and the underlying framework supports MCP.
Factory is free and lives in the main Mastra repository under Apache-2.0. Mastra separately sells its platform, starting with a free plan and then $250 a month plus usage.
