Welcome to rez’s documentation!

Rez is a cross-platform package manager with a difference. Using Rez you can create standalone environments configured for a given set of packages. However, unlike many other package managers, packages are not installed into these standalone environments. Instead, all package versions are installed into a central repository, and standalone environments reference these existing packages. This means that configured environments are lightweight, and very fast to create, often taking just a few seconds to configure despite containing hundreds of packages.

Traditional package manager:

Typical package managers install packages into an environment

Rez:

Rez installs packages once, and configures environments dynamically

Rez takes a list of package requests, and constructs the target environment, resolving all the necessary package dependencies. Any type of software package is supported - compiled, python, applications and libraries.
