Mazapan

Mazapan

An agentic desktop OS on Arch Linux.

Your coding agents are part of the desktop, every change to the system can be undone, and one theme runs from the boot menu to your editor.

Your agents, part of the desktop

Every coding agent's live sessions in the bar, each account's limits and spend in one place, a built-in MCP server, and changes to the system only through previewed steps you approve.

Updates you can undo

Arch's news before updating, an automatic rollback when a check fails, and checkpoints you can start from the boot menu.

Safe from the first boot

Full-disk encryption with a recovery key, one password for the disk and the account, and a firewall that lets nothing in.

Made for developers

Profiles for development, .NET and mobile, Claude Code, Codex, OpenCode and Gemini CLI ready, containers without root, databases in one click.

One look, everywhere

One theme for the whole system, from the boot menu to your editor, picked live or made from any picture.

A desktop that flows

Scrolling columns, an overview of every workspace, a command palette that finds apps, windows and settings, and a Control Center.
