Payments, auth, databases and AI APIs are the four integration categories that decide whether your AI-built app is a demo or a real product. Look for Stripe, a real database, OAuth logins and model APIs before you commit.
The demo always looks magic: type a sentence, watch an app appear. The real test comes the moment you need it to take a payment, remember a user, or talk to another service. That is where integrations decide everything.
Payments come first
If your app makes money, Stripe support is non-negotiable. The best AI builders wire up Stripe Checkout in a single prompt; weaker ones leave you copying keys into places you do not understand.
A real database, not just screens
Screens are easy. State is hard. Look for a builder that provisions a genuine database (Supabase and Postgres are the common ones) rather than faking persistence in the browser.
Authentication you did not have to build
Email-and-password is table stakes; social logins (Google, GitHub) separate the serious tools. Built-in auth means you are not hand-rolling the single most security-sensitive part of any app.
Model APIs for the AI features
Ironically, many AI app builders are weak at letting your app call an AI model. If you want your product to summarise, classify or chat, confirm it can reach OpenAI or Anthropic APIs cleanly.
Frequently asked questions
Do AI app builders support Stripe?
The leading ones do, and often wire up Stripe Checkout from a single prompt. Always confirm on the tool's own pricing or docs page before committing, since payment support varies by plan.
Can an AI-built app have real user logins?
Yes. Better builders include authentication with email and social logins out of the box, so you do not have to build the most security-sensitive part of the app yourself.
Which database do AI app builders use?
Most serious tools provision a real database such as Supabase or Postgres. Be cautious of builders that only simulate persistence in the browser, as that will not survive a real user base.
