Flox is a virtual environment and package manager that allows you to create portable environments with layered dependencies. You can install packages from a large open source repository and easily manage environments, build container images, and more. Flox aims to bring reproducibility and consistency to complex software development lifecycles by simplifying the management of dependencies. Originating from the D. E. Shaw group, Flox has proved invaluable in enterprise deployments of Nix. You can get help and contribute to Flox through their Discourse forum, Twitter account, or by filing issues on their repository. The Flox CLI is licensed under the GPLv2.
