No. Flutter, Laravel, Ruby on Rails, Vue, Stripe and Docker are what we run every day, and each case lists its stack. That is evidence of depth, not a limit: an audit starts from your code as it is.
Only if the audit shows a rewrite costs less than fixing what exists, and then the report says why, with specifics. Usually the right move is to keep the working parts and fix the risky ones.
You do. Repository, cloud, store listings and payment accounts stay in your name. We are added with the access the work needs and removed when you say so.
Yes: 30 minutes, no obligation. The initial audit is free too: a written report in 2–3 working days after we receive the agreed materials and access. You keep it even if you do not continue.
The first 30-minute call and initial audit are free. The audit report takes 2–3 working days after agreed materials and access are received. Delivery sprints start at $5,000; full rebuilds and AI MVP production projects are quoted for the agreed scope. Ongoing care starts at $990/month. Fixes, builds and implementation are paid work, agreed separately before starting.
Yes. Apps made with Lovable, Bolt, Replit, Cursor or FlutterFlow are ordinary code underneath. We check what those tools usually leave open: database access rules, keys in the client and payment webhooks.
We're a small studio based in Alicante, Spain. We work remotely, in English, with founders and companies in the US and Canada.
