[Open Source] Any good 100% open source SaaS NextJS Boilerplate?

Hi all,

I'm building an UI for our website's dashboard and (though I'm full-stack) I hate FE; hence, I'm looking for shortcuts to build a dashboard and revamp our landing page. So far, I've been playing with a few React/NextJS starters for SaaS, but all of them seem to have limitations:
- Either they're not completely open source and you have to pay for some functionality
- Or they use freemium based 3rd party providers for various things (ie. auth, database) which would lock one project in on long term

Do you guys know of any 100% open source template I could use?

PS. I would prefer Next over React or other framework.

Here are a few that I've saved:

- https://github.com/naufaldi/next-landing-vpn
- https://github.com/cruip/open-react-template
- https://github.com/sadmann7/skateshop

Dashboards & Components:

- https://github.com/kitloong/nextjs-dashboard
- https://github.com/horizon-ui/horizon-tailwind-react-nextjs

Hope this can come in handy.

Cheers

PS. There's plenty of them on the Github, just plug in the search term
