I'm not really following the "commits" but rather following releases. In the last 2 Years Kallithea had only 1 minor release (https://pypi.org/project/Kallithea/#history) 0.3 -> 0.4 without many new features. RhodeCode had 5 minor releases (https://docs.rhodecode.com/RhodeCode-Enterprise/release-note...) and multiple bugfix releases. I'm aware not all features in comparison are free, but we use the CE free version and it's enough for us at this point.
