One API key and one SDK for email, SMS, AI agent inboxes, scheduling, webhooks and more.

About the project

cosscom/coss is the official Cal.com design system, providing reusable interface components and related applications for building its web experiences. It is organized as a TypeScript monorepo, meaning multiple apps and shared packages live and develop together in one repository.

This repository also configures its own agents. See what coss tells them →
