A tiny shared Linux system

SSH in and get your own persistent little box — minimal by design, sandboxed, and yours to tinker with. A bit like the public “tildes”, but each user lives in their own container.

$ ssh -p 2222 <user>@mbox.blue

How it works

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

• Persistent — your home directory survives across sessions.
• Sandboxed — you’re isolated in your own container with your own resources.
• Minimal — a small Alpine userland, nothing bloated.

What’s inside

• Languages — Python, PHP and Go
• Editors — Vim, Nano
• Chat — irssi, WeeChat
• Web — curl, lynx
• Tooling — git, tmux, ssh
• Containers — box, to experiment with containers inside your box

Put yourself on the web

• A static page at https://mbox.blue/~you — just drop files in ~/public_html.
• A live app at https://you.mbox.blue — run a server in your box and publish its port. HTTPS is handled for you. See the docs.

Community

You’re not alone in here — mbox.blue is a little shared world.

• 👥 Browse the members and finger each other’s ~/.plan.
• ✍️ Sign the guestbook.
• 📊 Peek at the live status of the host.
• 🔗 Stitch your page into the webring so visitors can hop around.

Get started

$ ssh -p 2222 <user>@mbox.blue

💡 Your box keeps running after you disconnect — just SSH back in to pick up where you left off. Use tmux to keep interactive programs alive across disconnects.
