xitui is a library for making TUIs in Zig (requires version 0.15.1).

• Includes a widget and focus system.
• Widgets are put in a union type defined by the user, rather than using dynamic dispatch.
• Supports Windows, MacOS and Linux.

The only example I have right now is radargit, a TUI for git. Check out main.zig to see how a project is set up.
