wtf is ui?

Railly UI is a personal collection of pre-built user interface components that developers can drop into their web projects. Instead of building common UI elements like buttons, forms, or navigation bars from scratch, a developer can grab these ready-made pieces and customize them for their own app. The project is built to work with shadcn, a popular tool that lets developers copy component code directly into their codebase rather than installing them as a traditional package. To use a component, a developer runs a command in their terminal that points to a specific URL, and the component gets added to their project. They can also set up a shortcut in their project config so they can pull in components by name without typing the full address each time. This would appeal to developers who already use shadcn and want a curated set of extra components beyond what comes standard. For example, a solo founder building a SaaS dashboard might use this to quickly add a polished sidebar or data table without writing all the styling and markup themselves. Since it's described as a "personal registry," it seems like a collection one developer put together for their own use and chose to share publicly. On the technical side, the registry auto-deploys to GitHub Pages whenever changes are pushed, so the components are always available at a stable URL. It was built using a tool called Elements Studio, and developers can build the registry locally if they want to inspect or modify it before use. The README doesn't go into detail about which specific components are included, so you'd need to browse the registry URL to see what's actually available.
