What is it?

Dear PyGui is a Python GUI framework for building desktop interfaces quickly. It is built on Dear ImGui and uses an immediate-mode model with GPU rendering, with the core written in C/C++ and exposed to Python through a pip-installable package with minimal dependencies.

The toolkit covers common needs for script and tool builders: widgets with full theme and style control, a plotting API (via ImPlot) that can display over one million data points at 60 fps with zoom and pan, and a node editor (via imnodes). A canvas drawing API supports custom drawings and simple 2D games. Asynchronous function support and developer tools such as theme and resource inspection, runtime metrics and a debugger are included.

It runs on Windows 10 (DirectX 11), macOS (Metal), and Linux (OpenGL 3), with Raspberry Pi 4 listed on OpenGL ES. A built-in demo, runnable with python -m dearpygui.demo, shows the available widgets and serves as example code.
