GraphStudio is fully compiled to WebAssembly (multi-threaded) and runs directly in the browser.

The first load downloads ~11 MB (the wasm module, gzipped in transit; includes the Qt runtime) — depending on your network this may take a while; subsequent visits are served from the browser cache in under a second.

  • The page reloads itself once after opening — that is expected: the web build enables cross-origin isolation via a service worker (SharedArrayBuffer, required by multi-threaded wasm); after the reload the page runs in an isolated context.
  • In private/incognito windows (service workers disabled) the web build may fail to start — use the desktop build instead.
  • The OpenCV image subnodes and the JS scripting node are built in, so you can assemble and run compute graphs right away; the image-result panel renders statically on the web (the desktop build uses a GPU-accelerated viewer).
  • For heavy use, download the desktop installer for better performance and stability.
