WebShell
Use a minimal Alpine Linux shell directly in your browser.
Overview
WebShell is a browser-only Alpine Linux shell that boots directly into BusyBox ash through CheerpX. It has no desktop, app UI, multiplexer, or preinstalled package set, so you start with a small shell and add what you need after networking is ready.
Direct BusyBox shell
Start directly in Alpine Linux's /bin/sh with a minimal x86 minirootfs and no extra desktop layer.
Persistent local overlay
Changes made in the shell persist in the browser's IndexedDB overlay instead of modifying the immutable base image.
Tailscale networking
Authenticate in the browser and use an available Tailnet Exit Node when the shell needs public internet access.
Fullscreen PWA terminal
Use a responsive xterm.js terminal with WebGL rendering when available and automatic fallback when it is not.
Use and install
Open WebShell in a supported browser. HTTPS deployments can be installed as a standalone PWA from the browser menu.

Changes are written to the browser's IndexedDB overlay and persist locally while that browser storage remains available.
No. The app has no server-side runtime or Vercel Functions. The shell runs client-side in the browser.
