Show HN: I built a Next 15 SaaS boilerplate that makes web app development easy

Hi everyone,

how are you doing? Hope you also enjoy the summer weather :)

Most SaaS starter kits and boilerplates do not provide much in terms of web app functionalities.

The idea is to focus only on the web app part, providing a high quality, modern and flexible solution. Always go the extra mile, never take a shortcut.

Demo: https://demo.achromatic.dev

The tech stack is

- Next.js 15, React 19

- Auth.js v5

- Prisma

- shadcn/ui

- nuqs, next-safe-action, nice-modal

- TypeScript

- Tailwind

Everything is implemented using RSC and server actions.
