Supanext

Getting a SaaS app with user sign-up, a working database and a public blog live in days instead of weeks is the kind of job Supanext is built for.

Supanext is a Next.js and Supabase starter kit for SaaS and AI apps that comes with authentication and a database already set up, so the usual first stretch of project work is done before you write a line.

The kit also includes a modern landing page and a blog, both optimized for SEO, plus theme customization so your product does not look like every other template.

Supanext has AI integration examples too, which give you reference code for adding chat, text or image features instead of starting from an empty file.

Payments run through Stripe or LemonSqueezy.

This is a developer starter kit, so you should be comfortable with Next.js and Supabase, and it is not a no-code builder in practice.

Your app will depend on third-party services such as Supabase and the payment providers.

Pricing may put off hobbyists who just want to experiment.
