A word to the wise: similar to how foam is mostly air, Tauri is mostly marketing. Most of those 15MB "lightweight" bundles expand to 2 GB+ RAM in practice. Of course, devs still shamelessly (ignorantly, in all likelihood) call the apps "lightweight", while taking up, say, 6 GB of RAM for a 5 button UI. Tauri have also proven reticent [0] to correct the record. One supposes the sole advantage of sharing memory with other Tauri apps is not a sufficient sell to overcome Electron's single-browser-engine advantage.

A pure Rust app takes up ~60 MB for the same UI, with a large portion of that going towards graphics (wgpu table stakes).
