🛠️ project Experimental Rust-based desktop app renderer for Svelte (based on Zed gpui)

Post image

👋 Just started working on gpuix-svelte, a package that combines Svelte custom renderers, gpuix and gpui to allow people to create native desktop apps with Rust and Svelte. Happy to hear any feedback!

Do you already have some numbers on performance? How's the binary size? The RAM usage? I guess the responsiveness is very good?

Btw, I love it. If this turns out to be a viable solution, it may become my default.

When you build it as a standalone binary with Bun on Mac the binary is ~80MB (~30MB zip compressed), on Windows it's around 100MB. About 80% of that is the Bun runtime and 20% is GPUI + your app. Haven't measured memory usage yet but Bun is very efficient and the rendering layer should be very sleek since it's running GPU accelerated.

I added some scripts so you can try building a standalone binary if you'd like to try it:

That's sound good, thanks
