Questions about pricing
- What counts as usage?
- Everything your apps do while they run: visits to their pages, the time their server spends working, what their databases and files store and move, and the capabilities they use, like Ask AI. Each has a rate, listed on this page, and both plans use the same rates.
- What happens when my apps use up my monthly allowance?
- You'll see a heads-up in your dashboard at 80%. On Free, your apps pause until the next month starts, or until you upgrade. On Pro, they keep running and the extra usage is added to your next invoice at the same rates, up to a monthly cap, so a busy month never turns into a surprise bill.
- What does Pro include?
- Pro is $19.99 a month. It includes 3× the usage allowance of Free, as many apps as you like, and extra usage at the same rates when you need it.
- Do I need a card to start?
- No. Free needs only your email. You add a card when you upgrade to Pro.
- Do I pay for the AI that builds my apps?
- No. The AI you already use, like Claude, ChatGPT or Gemini, builds the app on your own plan with it. AppDen charges for running your apps, and for capabilities like Ask AI when your apps use them.
- Can I cancel Pro?
- Yes, any time, from Billing in your dashboard. Pro stays on until the end of the period you've paid for.
