opentui

OpenTUI is a library to build terminal user interfaces.

• It is written in Zig.
• You write TypeScript directly or through React and Solid.
• You arrange boxes and text with flexbox.
• You add selects, inputs, and scroll boxes with keyboard and mouse controls.
• You can play sounds, show images, and render 3D graphics.

OpenCode uses OpenTUI in production for millions of users.

Private packages

• @opentui/native - Private workspace with the Zig implementation, native tests, and benchmarks.

Install the OpenTUI documentation as a skill for your AI coding assistant with npx skills:

npx skills add https://opentui.com --skill opentui

Add -g to install the skill globally. The skill matches the latest release, and npx skills update moves it to each new release. Install from https://opentui.com/docs/next to follow the main branch. A skill installed with npx skills add anomalyco/opentui follows the main branch; run the command above to switch it to releases.

Development requires Bun 1.4.1 or later and Zig 0.16.0.

See AGENTS.md for engineering, tooling, and verification conventions.

bun install

Run package scripts from their package directory. Run bun run build from the repository root after you change native code or cross-package build outputs. Ordinary TypeScript changes do not require a root build.

Run repository tests and static checks from the repository root:

bun run test
bun run fmt:check
bun run lint

To link the source packages into a Bun-managed project, install that project's dependencies, then run ./scripts/link-opentui-dev.sh /path/to/project from the repository root. Add --react or --solid when needed.
