A decentralised cross-platform software installation system.

Works on Linux, Windows and macOS. Fully open source.

Run apps with a single click

Run applications without having to install them first. Control everything from a command-line or graphical interface.

You control your own computer

You don't have to guess what happens during installation. Mix and match stable and experimental apps on a single system.

Anyone can distribute software

Create one package that works on multiple platforms. Publish on any static web host; no central point of control. With dependency handling and automatic updates.

Security is central

Installing an app doesn't grant it administrator access. Digital signatures are always checked before new software is run. Apps can share libraries without having to trust each other.
