What is it?

OpenTUI is a library for building terminal user interfaces. Its native core is written in Zig and exposed through TypeScript bindings, so developers can write terminal apps directly in TypeScript or use React and Solid renderers to compose them.

Layout is handled with flexbox, letting you arrange boxes and text in the terminal. Built-in components include selects, inputs and scroll boxes, all with keyboard and mouse controls. The project also covers less common terminal features such as playing sounds, displaying images and rendering 3D graphics.

The monorepo ships several packages: core, React and Solid renderers, a key binding library, a QR code component, a Three.js WebGPU renderer and an SSH server integration. The project states that OpenCode uses it in production.
