Ultimate Multisite – WordPress Multisite SaaS & WaaS Platform


I've an Ultimate Multisite plugin user for a long time (Formerly known as and forked from WP Ultimo).



It solves everything I need to use Wordpress Multisite, instead of single WordPress instances, which saves a lot of time on only having one stack to update plugins on.



It is more cost-efficient for cheaper Wordpress hosting, as you're not paying for all the duplication of plugin storage and processing.



Well done for making this fantastic plugin open-source and community developed on GitHub.



Highly recommended!
