Dear ImGui Bundle

“Dear ImGui Bundle: easily create applications in Python and C++. Batteries included! With very few lines of code, you can build a responsive GUI, and deploy it to desktop or directly in the browser.”

Dear ImGui Bundle is a collection of libraries around Dear ImGui, for both C++ and Python. It focuses on rapid prototyping, tooling, and educational demos, with first‑class support for desktop and web.

Key features

• Cross‑platform: Windows, macOS, Linux, iOS, Android, and WebAssembly.
• C++ and Python APIs with very similar structure.
• Integrated ecosystem:
  • Dear ImGui (core widgets)
  • ImPlot / ImPlot3D (2D and 3D plotting)
  • ImmVision (image inspection)
  • imgui-node-editor, ImGuizmo, file dialogs, knobs, spinners, toggles, command palette, and more.
• Optional high‑level runners:
  • Hello ImGui: window, backend, docking, and assets management.
  • ImmApp: easy activation of add‑ons (ImPlot, Markdown, etc.).
• Web‑ready:
  • C++ via Emscripten
  • Python via Pyodide (online playground and deployable HTML templates)

“Think of it as a toolbox where all the pieces are pre‑wired to play well together: plotting, Markdown, node editors, image inspection, and more, ready to drop into your app.”

Interactive manual & demo

Click the image below to launch the interactive manual in your web browser:

The interactive manual showcases almost every part of the bundle with runnable examples. You can:

• Explore core Dear ImGui widgets.
• Try plotting, node editors, image viewers, test engine, and more.
• Inspect and copy the C++ and Python source code for each demo.

“The interactive manual is intended to be your live reference: browse widgets, run demos, and copy code snippets directly into your own projects.”

Online playground (Pyodide):

Run and edit Python ImGui Bundle apps directly in your browser:

• No installation.
• Type code on the left, see the interactive GUI on the right.
• Great for experimentation, teaching, and sharing small examples.
