In their own words
MES AI
MES AI is an open-source Manufacturing Execution System framework for teams adapting production workflows, integrations, and user experiences to their operations. Its design-time client configures products, routes, dispositions, equipment, plugins, and master data; its runtime handles work in process and shop-floor execution. The browser-based applications also include ERP and equipment simulators and a WIP client. Runtime functions cover dispatching, inventory activity, and hold or disposition handling. Built-in and custom plugins can extend the system with REST endpoints, event handlers, equipment behavior, dispatch strategies, and integration logic. A versioned REST API and WebSocket event stream provide near-real-time updates. PostgreSQL is the default database, with SQL Server and Oracle also supported. Optional integration work covers OPC UA, MQTT, SAP, SQL Server, Oracle, Modbus, Redis, STOMP, and AVEVA historian. The server uses authentication and role-based access control. MES AI runs on Linux, macOS, or Windows, with a FastAPI server and separate Vite clients. It is free and open source; test drives are available without authentication.
