ShaadKit is Seyed Mojtaba Shadab’s personal, opinionated foundation for starting Next.js projects—not a finished application. It brings together a set of tools and conventions intended to reduce repetitive setup while leaving developers free to adapt the foundation to their needs.
What ShaadKit is—and what it is not
ShaadKit is a public GitHub template repository for beginning Next.js work. Its README presents it as a frontend-focused foundation: a starting point for an application rather than a complete SaaS product or a system whose suitability for every production workload has been independently established.
The project reflects its maintainer’s choices about a useful starting stack. That makes it more opinionated than a bare framework setup, but its author describes the included capabilities as options that need not all be used at once. A team can adapt the foundation, though it should assess whether the defaults fit its own architecture and requirements.

What the README says is included
The current README documents the following stack and development tools:
#1 Best Overall
- Application: Next.js, React, and TypeScript.
- UI and styling: Mantine, Mantine Hooks, Mantine Form, PostCSS, CSS Modules, and Tabler Icons.
- Internationalization and data: next-intl and TanStack Query.
- Component development and testing: Storybook, Vitest, and Playwright.
- Code quality and validation: ESLint, Stylelint, and Arktype.
- Tooling: Bun, Bundle Analyzer, and React Compiler.
This is the repository’s documented stack, not an independently tested inventory. Versions and defaults may change, so check the README before adopting the template.
How the documented features fit together
UI, styling, and reusable components
Mantine supplies the UI library, with PostCSS and CSS Modules listed for styling. The README also documents integrated Image and Anchor components. The author describes these integrations as a way to connect Next.js functionality with Mantine components; they are design choices, not evidence of measured performance advantages over other approaches.
Internationalization
ShaadKit includes next-intl. The author says centralizing static text was useful alongside supporting multilingual projects. If your application needs more than one language—or you want translation-ready text organization from the outset—this is a meaningful default to review. If it does not fit your project, the author’s stated aim is that you need not use every included capability.
Data fetching, validation, and quality checks
The README lists TanStack Query for data fetching and Arktype for validation, alongside ESLint and Stylelint. These give a project established places to start for managing client-side data, validating values, and enforcing code conventions. The repository’s presence of these tools does not establish that its configuration meets a particular team’s requirements.
Components and tests
Storybook is documented for component development, with an accessibility addon and browser testing also described. Vitest and Playwright are listed for testing. This combination is relevant to teams that want to work on UI components separately and include both test and browser-test tooling in the starting project. The documented feature list should not be mistaken for a test result: the code and workflows have not been independently verified here.
Bundle analysis and environment setup
The README describes bundle analysis and environment validation as part of the foundation. These are useful areas to inspect when evaluating a starter, but their practical behavior depends on the repository’s current configuration and how a project uses it.
Why the author built it
In his explanation of the project, Shadab says that starting new Next.js projects repeatedly meant setting up linting, styling, tests, Storybook, internationalization, a UI library, and project conventions. ShaadKit is his response: a way to gather that recurring infrastructure in one foundation, rather than rebuilding it for each project.

ShaadKit starts with more decisions already made than a bare setup, while the author’s stated preference is for developers to adopt only the parts they need. There is no independently evaluated head-to-head comparison establishing that it saves a particular amount of time or is better than another starter.
Best Value
Who might find ShaadKit useful?
- Next.js developers who want a starting point with a UI library, styling conventions, and common development tools already selected.
- Multilingual projects that want next-intl included from the start.
- Teams building an MVP or SaaS product that expect to need component development, testing, and shared conventions as the project grows.
- Developers who value an integrated frontend workflow and are willing to review or change the defaults rather than treating them as mandatory.
The repository describes itself as primarily frontend-focused and says it may be adapted for full-stack use with changes. That is not a guarantee of production readiness, security, performance, or scalability for a particular application. Teams considering it for production should examine the current code, configuration, dependencies, and operational needs themselves.
Getting started
The README’s setup instructions at the time checked call for Node.js 24 or later and the latest Bun. Because setup requirements can change, consult the repository README before following these steps.
- Install Node.js 24 or later and the latest Bun.
- Clone the repository from GitHub.
- In the cloned project directory, install dependencies with
bun install. - Start the development server with
bun dev.
After the server starts, review the project’s README and configuration before building on the defaults, especially if you plan to remove tools or adapt the frontend foundation for full-stack use.
License and maintainer
The repository identifies Seyed Mojtaba Shadab (ShaadCode) as its builder and maintainer and states that ShaadKit is released under the MIT License. This describes the repository’s license; it does not set the license terms for every dependency in its stack. Check each dependency’s own license if that matters to your project.
