What breaks in apps an AI built, why it breaks, and what it costs when nobody looks. Written from the code we actually read.
This is not really a blog — it is a knowledge base, written and published straight from Memocore, our own product for keeping what a team knows.
The bill nobody capped
Runaway hosting and API bills usually come from traffic you never had. Where the real caps live, which ones are off by default, and what to check in one evening.
Nobody owns your app
The code records what your app does, never why. How to write the one page that gives you back the parts of your product you have quietly stopped touching.
Your API keys are in the browser
Keys the agent added to your frontend ship inside the JavaScript every visitor downloads. How to check yours in two minutes, and what to rotate first if one is there.
Stop asking the agent to fix it
The loop where every fix breaks something next to it comes from the shape of the request, not the model. What to change in the request, where to set boundaries, and when to stop.
What breaks in payments after the checkout works
Checkout is the part you tested, so it usually works. Renewals, failed charges and cancellations are the part nobody listens for. Five checks in the Stripe dashboard, and the order to fix them in.
Who can actually read your data
Access to other users' data is the most common break in apps built on Lovable and Supabase. Four checks you can run yourself in an evening, and what to do first if one fails.
