I got tired of managing two codebases for free and premium versions of my plugins. Every WordPress plugin developer knows the pain—you either maintain separate repos or rely on clunky add-on systems.

WP Plugin Builder is my solution. It's a set of build scripts that let you develop freemium plugins in a single codebase. Code block splitting between free and pro versions. Automatic tag replacement. React compilation for the block editor. Development mode with hot reloading.

It's built on WordPress Scripts, no extra dependencies like Gulp. Just write your code in the src folder, and it generates separate production-ready zip files for each version.

I open-sourced it because I think WordPress developers deserve better tooling. If you're building plugins professionally, this will save you hours every week.
