A NATIVE MAC APP FOR CURIOUS MINDS

Big ideas.
Little Boxes.

A Mac inside your Mac. Or a whole Linux machine.
Give your coding tools their own operating system.
Keep your everyday Mac out of the experiment.

YOUR NEXT EXPERIMENT STARTS HERELOCAL BY DESIGN

TWO WORLDS. ONE LITTLE APP.

macOS, meet macOS.
And Linux, too.

A full macOS guest for Mac-specific tools and experiments. Ubuntu Desktop for a Linux workspace. Ubuntu Server for the command line. Pick the environment your project needs.

LitterBox's image library includes macOS, Ubuntu Server and Ubuntu Desktop.
Official install images. Download once, reuse for your next Box.

A SMALL BOUNDARY. A LOT OF POSSIBILITY.

Your Mac is home.
Your Box is the workshop.

Try a new tool. Tinker with a dependency. Set up a coding agent. A Box gives the experiment a separate operating system and a disk of its own.

01 / CHOOSE

Pick your playground.

A macOS desktop, Ubuntu Desktop, or Ubuntu Server. Install media comes directly from Apple or Canonical.

02 / CONTAIN

You draw the boundaries.

Choose the CPU, memory, and disk. Turn guest networking off. Host folders stay unshared unless you choose to share them with a macOS Box.

03 / REPEAT

A fresh start feels good.

Keep a useful Box, clone a stopped one, or use Fresh Litter to return to its saved clean state. Toss a Box when its work is done.

NO EXTRA LAYERS BETWEEN YOU AND YOUR MACHINE

Runs on your Mac.

No LitterBox account.

Your tools. Your workspace.

Built with Apple's Virtualization framework. Set up your preferred tools inside the guest OS; LitterBox doesn't bundle an AI agent or connect to an AI provider.

MAKE ROOM FOR WHAT'S NEXT

A Box of possibilities.
