Opentui

Build terminal user interfaces with a modern component model. OpenTUI gives you a renderer that works like React or Solid but targets the terminal instead of the DOM, complete with flexbox layout via Yoga, keyboard input handling, and a plugin system. The documentation covers both framework bindings (React and Solid), core primitives like the renderer and audio playback, and practical concerns like keymaps and testing with snapshot support. If you're building CLI tools that need more than basic prompts or progress bars, this is the stack that lets you compose real UIs without fighting ncurses.

Files

OpenTUI Skill

Canonical reference docs are in the sibling docs/**/*.mdx files.

Inside the OpenTUI repository, this skill root is packages/web/src/content/. The same files are available under packages/web/src/content/docs/**/*.mdx from the repository root.

Terminal layout defaults

Design for a terminal app, not a browser. Use the available columns and rows efficiently.

Do not use gaps between adjacent UI panels.
Do not add unnecessary margins or padding.
Prefer compact, information-dense layouts over website-style card spacing.

Path invariant

/docs maps to docs/getting-started.mdx.
/docs/components maps to docs/components/overview.mdx.
Every other /docs/<slug> URL maps to docs/<slug>.mdx relative to this skill root.
From the repository root, prepend packages/web/src/content/ to each source path.
/docs/releases/<version> maps to docs/releases/<version>.md, the release notes of that version.
