Maintain a profitable Stripe-backed app with Replit
A commenter's Replit-built app reached about £20k in sales, and they use the agent to hunt duplications, organize code and add security like reCAPTCHA.
Done withReplit Agent
- What they did
- The commenter, a non-technical founder, first used Claude or ChatGPT to pressure-test ideas and make mockups, then copied those into Replit to build features and content. In Replit they regularly asked the agent to write tests, find and remove duplicate code, enforce naming consistency, and add security measures like Google reCAPTCHA; they said they learned through mistakes and even rebuilt from scratch after creating a mess.
- How it went
- They said one app monetized through Stripe has made about £20k in sales so far, a second is close to monetization, and a third with Stripe built in was planned within 30 days. They also said it was not easy, cost a good chunk to learn, and involved many errors.
- Worth knowing
- Their main warning was to expect to spend significantly to learn, and that they had to rebuild after months of development once the codebase became messy.
Try it yourself with Replit Agent
Review my existing app [app name or project] and look for duplicated code, messy organization and security gaps, such as missing bot protection on forms like reCAPTCHA. Give me a prioritized list of proposed fixes first. Then make the changes I approve and confirm that checkout and the other core flows still work. Do not touch payment settings or live data without asking me.
