A repository link or access to the project in Lovable, Bolt, Cursor, Claude Code, Codex, Base44, v0 or Replit. Read access is enough to start.
Challenge · Broken in production
Your Lovable, Bolt or Cursor app broke once real users arrived. Send the link. We read it first.
It worked in the demo. Then people signed up and something gave way: data showing to the wrong user, payments failing, sign-in looping, or a store review that came back rejected. 99 Francs® sends you a free written review within 48 hours, then fixes what blocks real users at a fixed price, paid when the work is done.
Free review, then one fix from US$1,000 or a full production pass at US$2,000–5,000.

What breaks first · and what the review checks
- Data one user can see of another
- Payments and webhooks
- Sign-in and sessions
- Errors nobody hears about
- Store rejection reasons
Direct answer
99 Francs repairs apps built with Lovable, Bolt, Cursor and similar tools that fail once real users arrive.
You give us access to the repository or the project. Within 48 hours you get a free written review of what breaks with real users, with a fixed price for the work. We keep your work and fix it rather than rewrite it, unless the review shows a rebuild is cheaper.
Signs you are here
When it breaks, it breaks in a few familiar ways:
Data is exposed
A user can read or change another user's records. Generated apps often ship with open database policies or keys in the front-end code. This is the first thing to close.
Payments are failing
Cards are charged but the account is not upgraded, a webhook is missed, or a refund leaves the user in the wrong state. Money paths have to be boring and tested.
Sign-in is broken
Password reset does not arrive, sessions expire in odd ways, or a social login works for you and not for them.
A store rejected the app
App Store or Google Play sent back a rejection and the fix is not obvious. Review rules, signing and privacy forms are their own piece of work.
Every change breaks something else
The tool rewrites files it was not asked to touch. Without a clear data model, each new prompt is a coin toss.
What we do
Stop the damage first, then make it solid.
The review ranks what is urgent. Exposed data and failing payments come before polish.

Fix what blocks users

Questions people ask before they write to us.
Apps built with Lovable, Bolt, Cursor, Claude Code, Codex, Base44, v0 and Replit. If the code lives in a repository we can read, or in a project we can be given access to, we can review it.
We reply within one working day. The written review then comes within 48 hours of you giving us access.
No, not by default. We keep your work and fix it. If the review shows that a rebuild is cheaper than fixing, we say so and quote it as an MVP instead.
The review is free. One fix starts at US$1,000. A full production pass runs US$2,000–5,000, depending on the state of the app. The price is fixed in writing after the review.
Then the MVP ranges apply: a web app is US$5,000–8,000 for a tight scope and US$8,000–15,000 for a bigger one. We tell you after the review, with the reasons, and you choose.
Yes. We read the rejection, fix what it names and resubmit, and we prepare and publish apps under your own developer account so the listing stays yours.
The price is fixed in writing after the review and paid once, when the work is done. There is no deposit.
