About Subscription App Builder
Build a paid web app with AI: user accounts, monthly subscriptions through Floot Payments (paid out via Stripe), a database and hosting, without writing code.
What is Floot?
Floot is an AI app builder with subscriptions, user accounts and a database built in, so you can launch a web app that charges customers every month without coding.
A paid app needs three things on top of the idea: accounts, a way to charge every month, and rules for what paying customers can use. Floot builds all three into the app with AI, so you can test a paid product without hiring a developer.
Why build it with Floot?
A paid app needs accounts, recurring billing and rules for what paying users get. Floot builds all three with AI, so you can test a paid product before hiring anyone.
How Floot works
Add Floot to the AI you already use from its listing in the Claude or ChatGPT directory, or the Cursor Marketplace. There is no address to copy.
- Describe the product and what paying customers get.
- Ask for sign-up, a pricing page and a monthly plan.
- Test checkout in test mode in the preview.
- Publish and switch payments to live.
For example, you could start with this prompt:
Build a web app where personal trainers create workout plans for clients. Trainers pay $19 a month after a 14-day trial; clients use it free. Use Floot Payments for the subscription.
