Users Can Access Paid Features Without Paying in a Lovable App

Quick Answer

The app is checking payment state in the browser instead of enforcing entitlements on the server or in the database. In practice this means users can bypass the UI and hit premium routes directly. Start with "Move entitlement checks to the backend" before making broader code changes.

Why this happens

The app is checking payment state in the browser instead of enforcing entitlements on the server or in the database. In practice this means users can bypass the UI and hit premium routes directly.

Fix

Move entitlement checks to the backend

Do not trust local state, query params, or hidden buttons. Premium access should be decided from a server-read subscription or order record tied to the signed-in user.

Store payment state in a real table

Use a dedicated subscriptions or entitlements table and only unlock access from webhook-confirmed records.

create table if not exists subscriptions (
  user_id uuid not null,
  stripe_customer_id text,
  stripe_subscription_id text,
  status text not null,
  current_period_end timestamptz,
  primary key (user_id)
);

Make Stripe update the record after payment

Your checkout alone should not grant access. The webhook should write the final paid status and your app should read only that source of truth.

Patch the generated access logic

Use a prompt that tells Lovable to remove any client-side premium bypasses.

Copy this prompt

Audit this app for any premium access checks that happen in the browser. Move paid feature gating to the server/database, read subscription state from Supabase, and only unlock access after a verified Stripe webhook updates the user's record.

Prevent this next time

Treat payments as a server-side authorization problem, not a UI toggle. If the browser can decide who is paid, the system is already too open.
