On Kallithea activity and release is better than rhodecode and truly open source under software conservancy. Kallithea do support svn and it has moved on, with turbogears 2 support and now the theme is also modern based on bootstrap.
I created RhodeCode, and know for sure Kallithea does not support SVN.
- RhodeCode is based on newer and more modern than turgobears2 framework, called Pyramid.
- RhodeCode had 20 releases since 2017, Kallithea had two.
- RhodeCode fixed many security issues that Kallithea didn't, not to mention dozen of features that RhodeCode has but Kallithea doesn't, e.g pull requests updates, integrations framework
