- https://lwn.net/Distributions/ lwn.net has a great list of Linux Distributions, and they seem willing to list new distributions as well.
- https://www.linux.com/directory/Distributions Linux.com has a decent list of distributions and you can submit yours to them as well.
More Difficult Distribution Sites:
- https://en.wikipedia.org/wiki/List_of_Linux_distributions The Wikipedia has a list of some Linux distributions, however distributors aren’t allowed to post information or edits about their own distributions. This is called a conflict of interest.
- distrowatch.com seems to be the most popular Linux distribution website, however sense 2004 (to our knowledge) no new distributions have been added.
