Zero Install

the antidote to app-stores

Anyone can distribute software

If you have a web-site, you can distribute your software;
Create one package that works everywhere;
With dependency handling and automatic updates;
There is no central point of control

Security is central

Installing a word-processor doesn't grant it administrator access;
Digital signatures are always checked before new software is run;
Users share libraries without having to trust each other;
Use with sandboxes and virtualisation is easy

You control your own computer

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

Zero Install is a decentralised cross-distribution software installation system. Other features include full support for shared libraries (with a SAT solver for dependency resolution), sharing between users, and integration with native platform package managers. It supports both binary and source packages, and works on Linux, OS X, Unix and Windows systems. It is fully Open Source.

0install 2.9 and 2.9.1 released, adding a "0install select --may-compile" option and some bug fixes. Our Travis tests now also test on OS X and, as a result, our test-suite now passes there.
