Tutorial

Use runtime profiles deliberately

A user in Development is not the same app user as a user with the same email address in Production. Runtime profiles isolate API keys, redirect URIs, provider settings, users, subscriptions, and diagnostics.

Recommended workflow

Use Development for local SDK testing and dev tunnels.
Use Production only with explicit public URLs and real provider settings.
Create separate Runtime Profile API keys for every profile.
Use the profile-specific Diagnostics page to generate the matching .env file.
