What are the gitlab counterparts for hg (mercurial)?

Question

git

I found
1. hglabhq.com but this project, unfortunately, is only for windows
2. https://rhodecode.com/ -- unfortunately, paid
3. https://bitbucket.org/sdorra/scm-manager/wiki /Home - did not take root with us due to an inconvenient interface (I understand that this is subjective).
Please tell me if I missed any worthy project?

Answer 1

kallithea-scm.org

Answer 2

HgLab (I am the author).
