FUXA is a full-stack web-based SCADA/HMI builder and runtime for industrial automation and IoT. It provides a visual editor (Angular + SVG) to create real-time dashboards, connect to field devices via 13+ protocols (Modbus, OPC UA, BACnet, Siemens S7, MQTT, etc.), and manage alarms, data acquisition (DAQ), scripting, scheduling, and user permissions. The backend (Node.js/Express) communicates with the frontend via Socket.IO for real-time device value updates. The system supports multiple time-series databases (SQLite, InfluxDB, QuestDB, TDengine) and can be deployed as a web server, Docker container, or Electron desktop app. It also integrates with Node-RED for low-code automation flows. The architecture is modular with a device driver factory pattern, JWT-based authentication, and a plugin system for extensibility. While the codebase is large and contains some monolithic components, it demonstrates solid engineering practices and has a rich set of reusable UI components and utility patterns.
ioBroker.vis is a visualization adapter for the ioBroker smart home platform, providing a web-based dashboard editor and runtime. It renders interactive views composed of widgets that bind to ioBroker data points (states/objects) via a real-time socket.io connection. The architecture is monolithic: a single-page application served by an ioBroker adapter, with all editor and runtime logic bundled in global JavaScript files using jQuery, CanJS, jQuery UI, and a homebrewed binding DSL. The widget system supports inline transformations (math, date formatting, JSON extraction) and extensibility via external widget sets. Development of this version has been officially stopped in favor of the rewritten vis-2 adapter, and the repository only receives critical fixes. The codebase exhibits significant technical drift due to outdated dependencies (jQuery 1.x, deprecated AppCache, IE8 polyfills), a monolithic design with tight coupling, and a license inconsistency (CC BY-NC in source files versus MIT in package.json). It is functional but should not be used for new projects.
