Desktop app vs. web version
Stacking uses the same WebGPU pipeline in both, so end results are identical. The desktop build changes what runs in the background and what depends on a network connection.
| Desktop app | Web (eise.app) | |
|---|---|---|
| Runs while minimized | Full speed | Throttled by the browser when the tab is backgrounded |
| Works offline | Fully offline after install | Needs a connection to load the app |
| Updates | Checks in the background, applies on next launch | Latest version on every page load |
| WebGPU | Always available (bundled Chromium with WebGPU enabled) | Depends on the browser (Chrome, Edge, and recent Safari support it; some browsers still fall back to the slower CPU path) |
| Stacking speed | Same. Both use WebGPU when available, so the compute is identical. | |
| Privacy | Same. All processing happens on your machine, no frames leave the device in either version. | |
| Install size | ~200 MB (bundled Chromium runtime) | Nothing to install |
