GitLab

Unfortunately Transifex is still a proprietary solution. Alternatively Weblate could be used instead to develop the future of Ring's translation. It's GNU GPLv3 and has a GitLab integration as well. So i think it will be a more ethical solution in the sense of Free Software and in the sense of GNU philosophy.

You will find more informations on their website https://weblate.org/en/ and in their latest docs as well https://docs.weblate.org/en/latest/

Here is a small article why another Free Software project (elementary OS) moved from Transifex to Weblate https://medium.com/elementaryos/adios-transifex-weve-gone-to-weblate-59870dea06b2
