There are basically three parts to this question, all of which can be chosen independently and then fit together.

First you choose a frontend (and often backend) framework to actually build the pages, like Next.js, Svelte, Laravel, etc.

Then, you can choose an auth solution like Clerk, auth0, NextAuth, Supabase, etc. Most of these products work with a wide variety of frameworks. Some of the frameworks (like Laravel) also have an auth framework built in.

For payments, you technically have choices but I would just use stripe.
