User Authentication in No-Code AI Apps

Built-in auth in modern no-code tools

Bubble, Softr, and Glide all offer built-in email/password and social login authentication — you rarely need to build auth from scratch. Enable it in your app's settings and configure what unauthenticated users can and can't see.

Gating AI features behind login

AI calls cost money per use — always require authentication before allowing access to any AI-powered feature, to prevent anonymous abuse from running up your API bill.

Basic usage limits per user

Add a simple "generations this month" counter field per user and check it before allowing a new AI call — this protects your costs even from legitimate, authenticated users on a free tier.

Key Takeaways

  • Modern no-code tools have built-in authentication — rarely build it from scratch.
  • Always gate AI-powered features behind authentication to prevent cost abuse.
  • Add a per-user usage counter to enforce reasonable limits.
  • Cost protection matters even in a fully no-code app.

Enable auth and a usage limit

Enable built-in authentication on your app, gate the AI feature behind login, and add a simple monthly usage counter per user.
