 Grit was created by Muke JohnBaptist, a full-stack developer who was tired of spending weeks setting up the same boilerplate for every project. Authentication, admin panels, file uploads, background jobs — they should just work. Now they do. One command, and you have a production-ready app. That's the framework he wanted to use, so he built it.
