@square-ui

A collection of 16 open-source full-layout application templates built with Next.js, TypeScript, Tailwind CSS, and shadcn/ui. Templates cover: Habit Tracker, Marketing Dashboard, Finance Tracker, Contacts, Inventory, Cookbook, Vault, Rentals, Bookmarks, Chat, Emails, Calendar, and more. Each ships in both Radix UI and Base UI variants. 14 of the 16 templates are paywalled under Square UI Pro ($169); 2 are free on GitHub. Use for: getting a complete, polished application shell — with charts, data tables, navigation, and domain-specific layouts — rather than building page structure from individual blocks.
