## What it is
Rez is a cross-platform package configuration, build, and deployment system that installs multiple versions of packages and dynamically resolves and configures runtime environments. It is an Academy Software Foundation (ASWF) project written in Python, widely used in VFX and animation pipelines.

## Use cases
- manage multiple versions of software packages side by side
- resolve and configure isolated runtime environments on demand
- build and deploy packages across linux, macos and windows
- reproducible tool environments for vfx and animation pipelines
- resolve package dependency versions into a working environment

## When to choose
- you need environment resolution for many coexisting package versions
- you run a multi-platform studio pipeline needing reproducible tool setups
- you want a pip/conda-style resolver for non-python binaries and tools

## When to avoid
- you only need simple python library dependency management (use pip or conda)
- you want container-based environment isolation instead of shell environment resolution
- your project has no need for multi-version package coexistence

## Facets
- artifact type: cli-tool
- maturity: active
- function: package-manager, build-tool, configuration-management, deployment, cli
- domain: developer-tools, cross-platform
