Lovable, Bolt, v0, Replit and Google AI Studio are excellent at proving an idea works. They are not built to carry it. We rebuild AI-generated prototypes into React and Node applications that survive real users — in four weeks, for a fixed price, with no downtime.
You keep the repository, the infrastructure and the IP. No lock-in.
AI coding tools optimise for a working demo, because that is what they are asked to produce. The failure modes are consistent enough to predict before we open the repository — and all four of these are things we find on nearly every audit.
No indexes, no foreign keys, no migration history. Queries that returned instantly against twelve demo rows take seconds against twelve thousand real ones.
Row-level security left permissive or switched off entirely, so any authenticated user can request any other user's records by changing an ID in the URL.
API keys and database credentials pasted inline where the generator put them, then pushed to a repository and never rotated.
The same rule reimplemented in four places. You fix the bug in the one you found and it stays live in the other three.
Generated code is rewritten into a maintainable React, Next.js or Node codebase with real separation of concerns, typed interfaces and a test suite — so the next developer who touches it can reason about it.
Off fragile local storage and unindexed tables onto PostgreSQL, Supabase or Neon, with a proper relational schema, enforced constraints and a migration history you can roll back.
The new architecture is built in parallel and traffic switches only after it has been tested against production data. Your users experience no interruption and no maintenance window.
Secrets moved into managed environment configuration and rotated, row-level security policies written and tested, authentication rebuilt against a real identity provider rather than generated scaffolding.
Query plans reviewed and indexed, N+1 patterns removed, caching added where it earns its place. Tested against realistic concurrency rather than a single demo session.
CI pipeline, staging environment, monitoring and rollback. Handed over with the repository and infrastructure accounts in your name.
The source tool changes the details, not the work. If your app was generated by any of these — or something not on the list — the audit tells you what it needs.
A full read of the existing codebase: what is salvageable, what has to go, where the security holes are, and what the data model should have been. You get the audit, a schema plan and a scalability roadmap as documents you keep whether or not you continue.
The new system is built alongside the old one on a clean React, Next.js and Node foundation. Your existing app stays live and keeps serving users throughout.
Production data is moved with verification on both sides, the new build is tested against it, and traffic switches over. No maintenance window, no downtime.
Repository, infrastructure accounts, documentation and deployment pipeline transfer to you. You own all of it, with no licence and no dependency on us to make future changes.
Straight answers on cost, timeline and what happens to your existing app.
Yes. TS Design Solutions migrates applications generated by Lovable, Bolt.new, v0, Replit, Base44, Cursor and Google AI Studio onto a custom React, Next.js and Node.js stack with a PostgreSQL, Supabase or Neon database. The source platform matters less than what it generated: the work is the same rebuild of data model, authentication and application logic.
TS Design Solutions charges £995 for an Architecture Blueprint (a full codebase audit, database schema plan, security scan and scalability roadmap, delivered in 48 hours), £9,995 for a Core Migration onto a clean React and Node stack in four weeks, and from £19,995 for a Scale-Up that adds complex features the AI tool could not build. Prices are fixed at the outset, not estimated hourly.
A Core Migration takes four weeks from kickoff to launch. Scale-Up projects that add new features, complex role-based permissions or third-party integrations run six to eight weeks. The 48-hour Architecture Blueprint is available first if you want the assessment before committing to a rebuild.
No. The replacement system is built in a parallel staging environment while the existing app keeps serving users. Traffic is switched over only once the new build has been tested against production data, so there is no maintenance window and no downtime.
AI coding tools optimise for producing something that demonstrates well, not something that survives concurrency. The recurring failure modes are database schemas with no indexes or foreign keys, authentication assembled from scaffolding with permissive or missing row-level security, secrets committed directly into the codebase, no migration history, and business logic duplicated across components so that fixing a bug in one place leaves it live in three others.
Yes. You own the repository, the infrastructure accounts and the intellectual property outright at handover. There is no proprietary framework, no licence to keep paying and no lock-in requiring TS Design Solutions for future changes.
Often, yes. Where the data model is sound, the work can be limited to hardening authentication, adding a migration history, extracting secrets and fixing the specific queries that fail under load. The £995 Architecture Blueprint exists to answer exactly this question before anyone commits to a full rebuild.
TS Design Solutions structures a limited number of engagements as revenue-share or earn-out arrangements rather than upfront fees, for products with demonstrated paying customers. This is assessed case by case against actual revenue, not projections.
