I am currently building ( https://nextacular.co ) for the past 10 days.
This will be open-source software. *Open for contributions* :D
Let me know what features you need maybe we can add them over at Nextacular, and also if you want to have early access to the repository.
Technologies involved are:
- Next.JS
- Tailwind CSS
- Stripe
- Prisma
- Next Auth
- Vercel
Regarding deployment, you can fork the repository and deploy it via Vercel.
We don't have file storage as of the moment, but this is definitely something we can consider as a plugin or extension.
