Why we built it
I started Common Ninja 7 years ago as a solution for myself to quickly generate beautiful html tables (which is still a pain to create by yourself). Some other people found it useful and started to create some tables of their own, and even started to pay for it.
During the next few years I created a few more plugins for pricing tables, feeds, charts, brackets, and initiated a partnership with Wix so they will sell my plugins on their store.
Common Ninja today has more than 80k registered users, and more than 600k plugins have been created with the platform.
