Some time ago, I have written an article about how to set up versioning for WordPress using git. I now came across an article by Newt Labs which have created an infographic about the justification for using git for WordPress. I think this infographic is quite insightful, so I will provide it below (with the kind permission of Newt Labs).
One thing which was of particular interest to me was that there was a handy list of alternatives to Revisr in the graphic. The alternatives are the following:
Personally I have only used Revisr, which worked fine for me. However, I am a bit concerned by their website greeting visitors with a warning about an expired SSL certificate. This should really have been fixed by now and is not building my trust in the tool.
