Dear ImGui Bundle is a framework built on top of Dear ImGui, for both C++ and Python. It comes with batteries included: plotting, Markdown, node editors, image inspection, and more.

See it in action:

No install needed!

• Launch the Interactive Explorer: a full demonstration: showcases all libraries with browsable C++ and Python source. Acts as a living reference manual.
• Open the Playground: a live python sandbox with ready to use demos, based on pyodide. Edit code, see results instantly.

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)
