Stylized preview. The real guide is interactive, not a screenshot.
Lovable is excellent at generating the interface and application logic, but a real backend, meaning your database and authentication, is a separate connection you set up once and then rely on.
A Lovable preview and a deployed, public app are two different things. These guides cover the deploy step, plus the specific errors people hit right after going live.
Want to build this for real instead of just reading about it?
No, but understanding a few backend and deployment basics, covered in these guides, will help you avoid the most common points where non-technical builders get stuck.
This is usually a missing environment variable or a database connection that was configured for preview but not carried over to production. See the deployment and Supabase guides for the exact fix.
Wiring up a real database early, even a simple one, is far easier than migrating from mock data once your app has real structure.
A feature that works in the Lovable preview can behave differently once deployed, especially around environment variables and routing.
You're not the problem. The format is. Here's what changes when you switch to an interactive mission.
