How many credits does an app take?

A simple landing page often takes 5–15 generations; an MVP with sign-in and payments typically 40–120. Small, precise prompts use fewer.

Do unused credits roll over?

Credits are topped up every month with your plan; check Settings → Billing for your current balance and renewal date.

For a first version, almost always. For a critical system, you still want a developer — vibe coding just means they start from something real.

Generations: Each prompt that builds or changes your app uses one credit. Reading, previewing and publishing do not.
Hosting: Publishing to a vantix.be address is included. Your own domain costs whatever your registrar charges.
Integrations: Services you connect — payments, email, databases — bill you directly at their own rates.
Review time: The hidden cost: checking what matters before launch. Budget it; it is cheaper than an incident.
Your time: Usually the biggest line. Clear prompts and small steps are how you keep it small.
