Not sure if I got it right, but if you want to build a simple backend I'd go with Supabase/Firebase for auth and Airtable for data/API. As for admin functionality — Retool seems to be the most powerful app (but can require some coding).

Also check out Memberstack — it allows to hide pages under paywall/authorization.

Here's a broader list of tools that we use.

No-code tools:

• Notion — documents (both internal project docs and public docs)

• Super.so, Tilda, Webflow, yep.so — landing pages and websites (also want to try popsy.so)

• Tally — forms

• Airtable — visual DB and API

• Figma, Canva — designs, prototypes, images, pitches

• Splitbee, Hotjar, Amplitude — analytics

• Crisp.chat, Intercom — customer support & analytics

• Make (Integromat), Zapier — automations

• MailerLite, SendGrid — transactional emails and newsletter

• Memberstack — membership/payments

Tech/low-code tools:

• Svelte — the simplest frontend framework to build (if you non-tech go with more popular React)

• Supabase, Firebase — auth+DB for prototypes

• Retool, Internal, UIBakery — back-office, admin functionality

• Render, DigitalOcean apps, Vercel — simplest hosting

• Napkin — simplest lambdas (eg. for simple backends with secret keys)

• GitHub Codespaces — coding without local env
