This is exactly why most devs just surrender and ship an 800MB Electron bundle for any cross-platform tool.

I finally got sick of that tradeoff. Ported a local video processing pipeline to Tauri v2 so it just uses the native macOS webview instead of fighting GTK or bundling Chromium. By hydrating heavy dependencies (like ffmpeg) via Rust at launch, the payload dropped to 30MB and idle RAM sits under 80MB.

Leaning on the native OS renderer is the only way cross-platform doesn't feel like a bloated compromise.
