Spins are alternate versions of Fedora Linux, tailored for various types of users via hand-picked application sets and other customizations.
We first offered Spins with the release of Fedora Linux 7 in May 2007. Previously, we distinguished between Spins—variants featuring non-default desktop environments—and Labs—variants tailored for a particular use case. While the websites still maintain this distinction, there is no practical difference. One day, we may even get the "Solutions" moniker to catch on.
Teams within Fedora are responsible for curating their Spins. The release-specific Spins listings on the sidebar have links to the maintainers for each Spin.
Each release, the Fedora Program Manager checks with each Spin maintainer to make sure they still want to keep their Spin active. If they do not, or if there is no reply, the Spin is offered to the community for adoption. Unmaintained Spins are dropped in order to make sure our users get the intended experience.
More information on creating spins is available in the Creating Spins documentation.
You can. Customized spins are merely targeted versions of Fedora Linux. It is possible to customize plain Fedora Linux to match any official spin. A customized spin can save you time and effort.
Custom spins let you experience a select set of Fedora software, possibly in a particular way. For example, a desktop live CD could boot directly to a GNOME desktop, with 3D desktop effects enabled and selected backgrounds, colors and featured applications. With further customization, a custom spin could boot directly to a movie player or launch a Web server that is ready to publish custom data.
