  Processor	Disk/ROM space	Memory
  24 MHZ	29 KB	9 KB

Cross platform

• Supported OSes: iOS/macOS/WathOS, Android, Linux, Windows, RTOS... or MCU without OS
• Supported languages: C/C++, Swift, Java, Javascript, C#, Golang...
• Supported 3rd party libraries: Qt, MFC, Winforms, CoCoa...

Useful features

• 🔣Multi-language, supports UTF-8
• 🔨Toolkit for building font/image resources
• 📐Layout GUI WYSIWYG
• ☁️Cloud + IoT Solution
• 📊Code Telemetry and Analysis in real time
• 📦Supports 3D and Web
• 🐋Run in docker with a single command: sudo docker run -it --privileged -v /dev:/dev-share idea4good/gui-lite:latest bash /run.sh

Easy to learn and support

Even a C beginner could master GuiLite quickly. The source code only uses basic C++ features (class, virtual function). We chose C++ as it could make the code size significantly smaller and easier to read.
