A high-performance TUI library with a Zig core, SolidJS frontend, and blazingly fast flexbox-like layouting.

⚠️ Alpha Software - This is a first working proof-of-concept. Nothing is finalized.

• Zig-based core exposed via Node API using napigen
• SolidJS with HMR for reactive UI development
• Node and Bun compatible runtime support
• Blazingly fast flexbox-like layouting powered by Clay and zclay
• Wide range of terminal features thanks to libvaxis (not yet exposed/used but can easily be added):
  • RGB colors, hyperlinks, bracketed paste
  • Kitty keyboard protocol, fancy underlines
  • Mouse shapes, system clipboard, notifications
  • Images via kitty graphics protocol

• ShadCN-like UI library - Fully customizable and themeable terminal-first components with shadcn CLI support
• DOM-like API - Handle input/scrolling/dragging in Zig core with optional JS hooks
• Zig-based animation library - Native performance animations
• Event bus framework - Bubbles/libvaxis-like event system for component communication without prop drilling
• Declarative routing - Built-in routing system

• ./native - Zig core library
• ./examples/solid-test - Example SolidJS application
• ./packages/core - Core TypeScript/SolidJS bindings

Requires Bun and Zig installed.

bun run build:native
bun install
cd examples/solid-test
bun run dev

cd examples/solid-test
bun run build
node ./dist/index.js

This project builds on the excellent work of:

• Clay by Nic Barker - High-performance 2D UI layout library
• zclay by johan0A - Zig bindings for Clay
• libvaxis by rockorager - Modern TUI library for Zig
• napigen by cztomsik - Comptime N-API bindings for Zig
