Scaling Qt from Desktop to Servers and Micro-controllers
summary
Qt moves from desktops to servers and MCUs by shrinking and isolating layers: copy-on-write value classes and pimpl consolidation cut allocations, a feature-system trims builds, and platform plugins abstract windowing and rendering. C++ back ends expose HTTP endpoints (Flask-like) and WebSocket/WebChannel bridges; WebGL streaming runs the same QML app in a browser (single-client limitation). WebAssembly offers zero‑deploy builds. A dedicated QML for MCU renderer runs 60 FPS UIs with framebuffer ~3 MB and SRAM footprints near 226 KB. WebGL streaming and the embedded MCU demo work today.
