  • ⚡Fast: High Rendering performance, even work on MCU

  • 👫🏻Compatible: Work smoothly with 3rd party frameworks(Qt/MFC/Winform/Cocoa/Web)

  • ⚙️️Hardware Minimum Requirements:

    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;📀Playback Video
  • 🔨Toolkit for building font/image resources
  • 📐Layout GUI WYSIWYG
  • ☁️Cloud + IoT Solution
  • 📊Code Telemetry and Analysis in real time(remove .sh/.bat files if dislike to share)
  • 📦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 /

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.
