Any of these Git repositories can be cloned read-only via HTTP(S). For example:
git clone https://22wlp.org/~gautampk/repo/n.git/
Most of the repos are also hosted on GitHub. For example, the above repository is also available at:
github.com/gautampk/n/
This would be a better option for a remote if you are looking to collaborate and may want to submit a pull request in the future.
