+There are also more advanced web-based development environments that
+include ability to manage users, groups and projects; private, group
+and public repositories; and often include issue trackers, wiki pages,
+pull requests and other tools for development and communication. Among
+these environments are `Kallithea <https://kallithea-scm.org/>`_ and
+`pagure <https://pagure.io/>`_, both are written in Python; `Gogs
+<http://gogs.io/>`_ is written in Go; when its development seemed to
+be stagnated there was a fork `Gitea <http://gitea.io/>`_, still
+active.
+
+And last but not least `Gitlab <https://about.gitlab.com/>`_. It's
+perhaps the most advanced web-based development environment. Written
+in Ruby, community edition is free and open source (MIT license).
