An HMI graphics library typically provides:
| Feature | Why It Matters | |--------|----------------| | | Scales from 2" to 4K without pixelation | | State-based styling | Shows “pump running” (green) vs “alarm” (red) without swapping images | | Touch-friendly sizing | Minimum 40×40px hit area for finger operation | | Tool compatibility | Works with Ignition Maker, Grafana, Node-RED, FUXA, or your custom Web HMI | | No restrictive license | Avoid GPL if building proprietary hardware – prefer MIT, CC0, or Apache 2.0 | free hmi graphics library
: A go-to for minimalist, professional iconography. It features thousands of industrial symbols that are perfect for modern, clean HMI designs. HMI Project (Free Library) An HMI graphics library typically provides: | Feature
| | Primary Use Case | Key Strengths | Considerations | | :--- | :--- | :--- | :--- | | Embedded / Microcontrollers (MCUs) |||| | LVGL | Resource-constrained embedded devices (smart home, wearables, medical). | Ultra-lightweight (64 kB Flash, 16 kB RAM), 30+ built-in widgets, advanced graphics effects, MIT license for free commercial use. | Requires C programming expertise; lacks the raw graphical performance of Qt for high-end systems. | | GT-HMI | Embedded GUI design for domestic (Chinese) markets, specifically for LCD screens. | Free, "permanent" design software and open-source engine; low memory footprint; comes with a rich set of industrial-grade widgets and multi-language support. | Ecosystem and documentation are largely in Chinese, which could be a barrier for some. | | Web / PC-Based (SCADA Focused) |||| | FUXA | Rapid, modern web-based HMI/SCADA for IoT and remote monitoring. | Pure web-based (HTML5) designer, low-code / drag-and-drop, supports multiple industrial protocols (Modbus, MQTT, OPC UA). | May have a less mature feature set for very large-scale, complex SCADA systems compared to enterprise solutions. | | Rapid SCADA | Full-featured SCADA/HMI for mid-to-large scale factory automation. | Comprehensive platform with built-in HMI designer, alarm management, reporting, and unlimited tags; highly extensible in C#/.NET. | Less "drag-and-drop" than FUXA; requires more initial setup and .NET skills for deep customization. | | AdvancedHMI | Windows-based, desktop SCADA development, especially for C# developers. | Seamless integration with Visual Studio, provides 20+ native PLC drivers (Modbus, Siemens, etc.), and easy drag-and-drop HMI design. | Primarily for the Windows ecosystem; the UI is based on WinForms, which may feel dated for modern web applications. | | Ultra-lightweight (64 kB Flash, 16 kB RAM),
