Design system · AGPL-3.0 · data updated 2026-07-08

The official Cal.com design system, formerly known as Origin UI, now under coss.com/ui. A modern, TypeScript-first component library built on Base UI (not Radix UI), designed for developers and AI-assisted tooling. Covers standard UI primitives with Cal.com's visual language — clean, minimal, developer-focused. Monorepo includes apps/origin legacy components. Free and open source. Use for: adopting the Cal.com design system's Base UI primitives when you want an alternative to Radix-based shadcn with a battle-tested real-world design system behind it.
