OpenTUI

OpenTUI is a native terminal UI core written in Zig with TypeScript bindings. The native core exposes a C ABI and can be used from any language. OpenTUI powers OpenCode in production today. It is an extensible core with a focus on correctness, stability, and high performance. It provides a component-based architecture with flexible layout capabilities, allowing you to create complex terminal applications.

This monorepo contains the following packages:

• @opentui/native - Private workspace package containing the Zig implementation, tests, and benchmarks.
• @opentui/core - TypeScript bindings for OpenTUI's native Zig core, with an imperative API and all primitives.
• @opentui/three - Three.js WebGPU renderer for OpenTUI.
• @opentui/solid - The SolidJS reconciler for OpenTUI.
• @opentui/react - The React reconciler for OpenTUI.
• @opentui/keymap - Shared command, keybinding, and sequence engine.
• @opentui/qrcode - QR encoder and terminal renderable integrations.
• @opentui/ssh - Serve imperative, React, and Solid OpenTUI applications over SSH.
• @opentui/examples - Example browser and standalone examples executable build.
• @opentui/web - Private documentation website and installable AI agent skill source.

Install

NOTE: You must have Zig installed on your system to build the packages.

TypeScript/JavaScript

bun install @opentui/core

AI Agent Skill

Teach your AI coding assistant OpenTUI's APIs and patterns.

Universal skill install with npx skills:

npx skills add anomalyco/opentui --skill opentui

Install globally for every project:

npx skills add anomalyco/opentui --skill opentui -g

OpenCode uses the same install command. No separate installer is needed.
