VersionPress

VersionPress is a free and open-source plugin that brings the full power of Git to WordPress. Its key strength is that it version-controls not just files but also the database. VersionPress automatically creates Git commits for both file and database changes, in natural language. Plugins break, people make mistakes; sometimes, you just want that good old Undo button. Git took the pain out of file merging; VersionPress does the same for WP database. You can push to GitHub, your colleagues pull and make the site fully functional in seconds. MySQL is a cache. VersionPress can store hundreds of full site snapshots to just a few megabytes. We care about UX deeply. VersionPress should not be a low-level tool for geeks. It works fine on simpler sites and you're encouraged to try it in your development workflows but it is not production-ready yet.
