Rvst renders Svelte components natively using a pure Rust pipeline — no webview, no Electron, no browser engine. Write standard Svelte 5. Get a real desktop app. The stack: Taffy for layout, Parley for text, Vello for GPU rendering. Your Svelte code compiles to the same component tree, but renders through Rust instead of a browser. Open source (Apache 2.0). Built for developers who want fast, lightweight desktop apps without shipping a browser.
Hey PH — I'm Shane, the creator of rvst.
I've been building AI coordination systems and kept hitting the same wall: Electron apps are bloated, slow, and ship an entire browser just to render a UI.
So I built a Rust rendering engine that runs Svelte components natively. No webview. No Chromium. Your Svelte code, rendered directly through Taffy (layout), Parley (text), and Vello (GPU paint).
Why Svelte specifically? It compiles to minimal JS with no virtual DOM — which makes it the cleanest target for a non-browser renderer.
What's working today:
- Svelte 5 component rendering
- CSS layout via Taffy
- Text rendering via Parley
- ASCII inspector for debugging render trees
What I'd love feedback on:
- Which use cases would you actually build with this?
- What's missing that would make you try it this week?
