Zero Install

Zero Install is a decentralized cross-platform software installation system under the LGPL. It allows software developers to publish programs directly from their own websites while supporting familiar features from central distribution repositories such as shared libraries, automatic updates, and digital signatures. It is designed to complement rather than replace the operating system's package management. 0install packages never interact with those provided by the distribution.

It allows you to run programs without installing them. No need to guess what will happen during installation. Mix and match stable and experimental applications in one system.

Create a package that works on multiple platforms. Publish on any static web host; There is no central control point. With dependency management and automatic updates.
