Feature request - Login Page and Firebase integration

Hi Base44 team,

I’m building a women’s health app, Luna, and I’d like to request a few features to support our subscription model and compliance requirements.

Goal:
Allow users to log into the app only after subscribing through an external website (Stripe) — similar to how Spotify handles memberships. This setup avoids in-app purchases and App Store/Google Play’s 30% transaction fees.

Feature requests:

1. Firebase Integration

   • Use Firebase Authentication to manage user sign-up, login, and profile data.

   • Store basic user data and subscription status within Firebase.

2. Editable Login Page / Paywall Flow

   • Allow customisation of the login/onboarding screen so users are clearly guided to subscribe via our external website.

   • The login flow should:

     • Direct new users to the website for membership sign-up.

     • Let returning users log in to check their subscription status.

3. Stripe + Webhook Flow

   • Stripe (via our website) sends a webhook to Firebase when a payment is successful.

   • Firebase updates the user’s subscription record (e.g., subscriptionStatus: active).

   • Firebase then triggers a webhook or API call to Base44’s backend to update the user’s status in your system so the app unlocks.

Example flow:

1. User downloads Luna and logs in (Firebase Auth).

2. App checks Base44 → sees subscriptionStatus: inactive.

3. App shows “Subscribe via website” screen.

4. User pays on website (Stripe).

5. Stripe webhook → Firebase (subscriptionStatus: active).

6. Firebase webhook → Base44 backend → App unlocks features.

Thank you so much — I want to make sure this setup is both smooth for users and technically clean for the team.

Warmly,
Alessia Millsom
