Try it in StackBlitz.
StackBlitz boots the repository's playground/ SvelteKit app
in a WebContainer and runs the full Vite dev server — DevTools panels
included. No install required.
How to use.
- 01
Run
Click "Run this project" on the embed. StackBlitz clones the repo, installs deps via pnpm, and runs pnpm dev.
- 02
Open DevTools
Once the dev server is up, click the Vite DevTools floating button in the preview to open the DevTools UI.
- 03
Explore
The Svelte panels — Components, Reactive Graph, Profiler, and more — appear in the DevTools sidebar.
⚐ WebContainers run entirely in your browser — no code is sent to a server. First boot can take 30–60 seconds while dependencies install.
