Show HN: Open-source Next.js dashboard starter with auth, RBAC and Storybook

Hey HN, I'm Matt. Recently I've been working on an open-source Next.js dashboard starter - the goal was to have things like auth, RBAC, theming, i18n and accessibility ready out of the box so you don't have to build them from scratch with every new project.

It comes with 90+ reusable components built on top of Shadcn UI plus 60+ chart variations from Recharts, all documented in the included Storybook. There is also an optional Node.js backend which enables the full Better-Auth flow, and a separate, lightweight version of the starter with just the layout and the core setup.
