Chalk UI is an open-source React component library styled with TailwindCSS and built for Next.js SaaS applications, providing opinionated, flexible components for building dashboards and admin interfaces.
What is Chalk UI?
Chalk UI is a React component library rather than a full website template. It takes React components as input and renders styled, accessible UI elements as output. It is designed specifically for Next.js projects and uses TailwindCSS for styling. The project is open-source under the MIT License and draws inspiration from shadcn/ui, Tremor, and Saas UI, while building on Radix UI for its component primitives.
Key Features
- Opinionated and flexible components — Components are designed with SaaS application patterns in mind, but remain customizable through Tailwind classes and component props.
- TailwindCSS styling — Every component is styled with TailwindCSS, using class-variance-authority for variant management and tailwind-merge to avoid class conflicts.
- Next.js optimized — Built specifically for Next.js SaaS apps, integrating with the React server component and client component model.
- Form integrations — Includes specialized form components and integrations: React Hook Form with zod validation, react-phone-number-input for phone fields, react-currency-input-field for currency, react-dropzone for file uploads, and react-day-picker for date selection.
- Accessible primitives — Built on Radix UI, providing keyboard navigation, focus management, and ARIA attributes out of the box.
- Icon support — Uses Lucide icons for a consistent, lightweight icon set.
- Data grid support — The repository's topics list data-grid and tanstack-table, indicating a data grid component built on TanStack Table.
- MIT licensed — Free to use, modify, and distribute in both commercial and personal projects.
Who is it for?
- Next.js SaaS developers who need a ready-made set of UI components for admin dashboards, settings pages, and user management interfaces without writing HTML and CSS from scratch.
- Frontend engineers who want a component library that follows accessibility best practices via Radix UI and integrates with a TailwindCSS-based design system.
- Indie hackers and startups building a SaaS MVP quickly, using the component library to ship polished interfaces in less time.
What can you do with Chalk UI?
- Build a customer dashboard: Compose layout components, data grids, and charts to display key metrics and user data.
- Create complex forms: Use the form components with React Hook Form and zod to build validated multi-step onboarding, billing, or profile forms.
- Assemble admin panels: Combine Radix-backed dialog, dropdown, and popover components with Tailwind styling to create consistent administrative tools.

- shadcn/ui — a popular copy-paste React component library also built on Radix UI and Tailwind.
- Tremor — a React library focused on dashboards and data visualization.
- Saas UI — a component library and pro template for building SaaS products with Chakra UI.

What tech stack does Chalk UI use?
Chalk UI is built with React, styled with TailwindCSS, and leverages Radix UI primitives. It also integrates with React Hook Form, zod, Lucide icons, and includes components for phone, currency, file upload, and date inputs.
Does Chalk UI work with other frameworks besides Next.js?
The library is explicitly built for Next.js SaaS applications. Since it is React-based, components may work in other React frameworks, but the project does not document support for non-Next.js setups.
