WebDevStudios has launched Pluginize, which is a plugin store where they’ll share and sell self-created WordPress plugins. I’ll say that this wasn’t much of a surprise to me as I learned about it — WebDevStudios employees are constantly publishing new plugins and CMB extensions.
They currently have two free and two paid plugins. It will be interesting to see how the store expands over the course of 2016, and if any agencies might follow their example.
