blockusStarted in a single repo. Stayed there.
The first version of blockus was a private folder of components we copy-pasted between client projects. Each time, we cleaned it up a little more. After the tenth project we realized we were maintaining a catalog — so we made it official.
We kept the scope narrow on purpose. No drag-and-drop builder, no proprietary runtime. Just React files that look exactly like the code your team already writes, dropped straight into your repo via the shadcn CLI.
“Constraints make better products. We ship fewer sections and make each one count.”
