A tiny shared Linux system

SSH in and get your own persistent little box — minimal by design, sandboxed,<br>and yours to tinker with. A bit like the public &ldquo;tildes&rdquo;, but each user lives<br>in their own container.

$ ssh -p 2222 @mbox.blue

How it works

When you connect over SSH you&rsquo;re dropped straight into your own<br>container — powered by sshbox and<br>box, a tiny container runtime. Your box<br>keeps running between logins, so your files and background processes are right<br>where you left them.

Persistent — your home directory survives across sessions.

Sandboxed — you&rsquo;re isolated in your own container with your own resources.

Minimal — a small Alpine userland, nothing bloated.

Put yourself on the web

A static page at https://mbox.blue/~you — just drop files in<br>~/public_html.

A live app at https://you.mbox.blue — run a server in your box and<br>publish its port. HTTPS is handled for you. See the<br>docs.
