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.

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

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.
You’re not alone in here — mbox.blue is a little shared world.
- 👥 Browse the members and
fingereach 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.
