What Zero Install is
Zero Install is a free, open-source system for running applications without first using a traditional system installer. Developers can publish software on their own websites, and feeds can be hosted on ordinary websites, without requiring a central app catalog. Zero Install resolves dependencies, shares libraries where possible and allows conflicting versions to coexist. It checks for updates automatically, with a configurable check frequency, and verifies package signatures before new software runs.
Users can cache packages without root privileges; caching does not run package code or write to system software directories, and using the system does not affect other users of the computer. Zero Install can use packages installed by a Linux distribution and PackageKit for system packages when a Zero Install package is unavailable. Downloads are offered for Linux, Windows and macOS, while source builds can run on most Unix-like systems. Developer resources include Python, .NET and JSON APIs, and tools for publishing, testing, mirroring and managing feeds. The project began in 2003 and is developed by volunteers around the world.
Who it suits
Zero Install may suit users who want to run applications without a traditional installer and developers publishing software through website-hosted feeds. Its dependency handling and developer tools may also serve people managing software packages across platforms.
