Hero features

☁️Cloud + IoT Solution: master your IoT business all over the world
🔣Multi-language, supports UTF-8;📀Playback Video
🔨Toolkit for building font/image resources
📐Layout GUI WYSIWYG
📊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 /run.sh

Easy to learn and support

Even a C beginner could master GUI-lite 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.
