A collection of beautifully designed, accessible, and customizable terminal UI components. Built on Ink and OpenTUI. Works with shadcn/ui.

How do I publish components with termcn?

Add or edit components under registry/bases/ink/ or registry/bases/opentui/, register them in registry.json, run pnpm registry:build (which refreshes public/r/), then deploy. Consumers install with npx shadcn@latest add against your published registry URL.

Is termcn open source?

Yes. The source is on GitHub and released under the MIT License.

Notes

Accessibility

termcn exposes the following behavior through Ink's terminal accessibility APIs. This is not a browser ARIA or general WCAG-conformance claim.

Keyboard: Enter / Space activate the focused action when enabled; Escape dismisses or cancels when supported; Tab / Shift+Tab move through Ink focus targets.
Focus and composition: Input is active only while the component's focus target is focused, enabled, active, and inside the topmost focus scope.
Screen reader: Screen-reader mode removes decorative output while preserving meaningful labels and state.
