NextUpKit Is Now Open Source!

We're thrilled to announce that NextUpKit is now completely free and open source!

What Changed?

NextUpKit was previously a paid Next.js SaaS starter kit. We've decided to open source the entire project so that every developer can use it to build their next SaaS — without paying a dime.

The full source code is now available on GitHub for anyone to use, modify, and contribute to.

Why Open Source?

We believe the best developer tools are the ones everyone can access. By going open source, we're making it possible for:

  • Solo developers to launch their SaaS ideas without upfront costs
  • Teams to customize every part of the stack to fit their needs
  • Students and learners to study a real-world production codebase
  • The community to shape the future of the project through contributions

What's Included?

NextUpKit comes packed with everything you need to ship a SaaS product:

  • Authentication — Full auth flow out of the box
  • Payments — Stripe integration ready to go
  • Database — Prisma ORM with a solid schema
  • Email — Transactional email support
  • Theming — Light and dark mode with customizable design
  • Analytics — Built-in analytics setup
  • And more — all completely free

Get Started

Clone the repo, install dependencies, and start building. It's that simple.

We'd love for you to give NextUpKit a try. If you find it useful, star the repo on GitHub and share it with other developers.

Contributing

NextUpKit is now community-driven. We welcome contributions of all kinds — bug fixes, new features, documentation improvements, and more. Check out the repo to get involved.

Let's build something great together.
