Show HN: Full Python GUI apps in the browser – no JavaScript, no server I have been working on Dear ImGui Bundle since 2022, but it is the first time I talk about it here. It is a framework around Dear ImGui for building interactive applications in Python and C++. It comes with batteries included: Plotting, image inspection, Markdown, node editors, 3D gizmos, knobs, toggles, etc. https://imgui-bundle.pages.dev It now also runs smoothly in the browser via pyodide: The playground below is a python app running in your browser (no server, no JavaScript). You can edit the code on the left and click Run. It even works on mobile. https://imgui-bundle.pages.dev/playground I have a strong interest in providing tools that help others express their creativity. This project aims to be a step in this direction as it helps develop GUIs where the code is extremely readable & hackable. Some of the goals it addresses: - Bring true Immediate Mode GUI to Python and C++ - A versatile range of high quality libraries: Widgets, Plots, Image Analysis, Node edition, markdown rendering - Multiplatform apps in C++: works on all platform in C++ (desktop, mobile, emscripten) - Deploy python apps to the web - High quality python bindings that are always up-to-date (because they are auto-generated) - Smooth transition between C++ and Python (same APIs for both) I'd be happy to answer questions! https://ift.tt/0IejxnX May 7, 2026 at 11:06PM
