Taking a vibe coded app from prototype to production means keeping the screens and workflows that work, fixing security and backend weaknesses, and rebuilding components that cannot safely support real users or transactions.

Whether you built your prototype using Lovable, Bolt, v0, Replit, Cursor, or Claude Code, you need to understand what is ready for launch before investing further.

Before hiring an MVP development company, I recommend evaluating each component for reuse, repair, or replacement.

In this guide, I’ll explain how to make those decisions, what each AI builder leaves you with, the estimated costs and timelines, and what investors examine during technical due diligence.

 

Key Takeaways

  • Keep validated screens and workflows while addressing security, data integrity, and backend reliability.
  • Start with an audit, typically estimated at $3,000-$8,000 over 1-2 weeks.
  • AppVerticals estimates $15,000-$35,000 for security hardening and $20,000-$60,000 for targeted rebuilding, subject to discovery.
  • Investors review code ownership, security, architecture, and maintainability.

 

What Prototype to Production Means for a Vibe-Coded MVP

For a vibe-coded MVP, moving from prototype to production means preparing AI-generated software to handle real users, secure transactions, and ongoing operations.

Andrej Karpathy introduced the term vibe coding in February 2025. Software developer Simon Willison later defined it as:

      “building software with an LLM without reviewing the code it writes.”

While AI tools accelerate early development, production introduces additional requirements for reliability, security, and maintainability.

 

Stage Who uses it What it needs
Prototype Founders, stakeholders, early testers Demonstration flows, sample data, concept validation
MVP Real users and pilot customers Functional workflows, secure data handling, reliable backend
Production Active customers and operations teams Monitoring, backups, access controls, tested releases, operational support

For a more detailed comparison, see our POC vs prototype vs MVP guide.

Why Vibe-Coded Prototypes Break Before Launch

Vibe coding to production becomes challenging when applications encounter concurrent users, interrupted transactions, unexpected inputs, and operational failures.

Common weaknesses in AI-generated applications include incomplete workflows, inconsistent code structures, and insufficient error handling. These weaknesses create AI technical debt and increase maintenance costs as the product grows.

The risks of inadequate controls are also visible in AI development tools. In July 2025, Replit’s agent reportedly deleted production data during testing. CEO Amjad Masad told Fortune the incident was:

“Unacceptable and should never be possible.”

Replit subsequently introduced additional database separation safeguards.

Security Gaps Are the First Fix

Security remains a major concern when moving AI-generated applications into production. Veracode’s October 2026 report found that AI-generated code passed security tests only 62% of the time.

The disputed CVE-2025-48757 highlighted database access-control concerns in Lovable-generated applications. This aligns with the OWASP Top 10:2025, which ranks Broken Access Control as its leading risk.

Prioritize server-side authorization, secure credential management, and dependency checks before launch.

Audit the Prototype Before You Change Anything

Before starting a technical audit, gather access to the source repository, AI builder account, database backups, environment configurations, and third-party services.

Prototype audit flow: five access items feed a technical audit that outputs a prioritized remediation roadmap

As Simon Willison puts it:

“I won’t commit any code to my repository if I couldn’t explain exactly what it does to somebody else.”

I use this principle to assess whether developers can understand, maintain, and safely extend the existing code. The final deliverable is a prioritized remediation roadmap with dependencies and estimated effort.

For more details, explore our code audit guide.

Keep, Fix or Rebuild: A Component-by-Component Decision Table

The decision to keep, fix, or rebuild depends on whether each component meets the product’s functional, security, and maintainability requirements.

I use the following checks to establish an initial recommendation.

Component  Keep when  Fix when  Rebuild when 
UI and screens  Matches validated designs  Missing loading or error states  Business logic mixed into UI
User flows Users completed flows during testing Navigation, retries, or empty states fail  Flows depend entirely on demo data 
Sign-in and roles  Platform authentication enforces server-side authorization Roles are checked only in UI  Custom authentication lacks reliable role controls
Data model  Supports relationships and migrations Needs constraints, indexes, or access policies  Cannot support tenants, history, or relationships 
Business logic  Runs server-side with tests Duplicated or untested logic  Browser controls pricing, limits, or permissions 
Payments and webhooks  Hosted checkout and verified webhooks Missing idempotency or retry handling  Client controls prices or stores card data 
Integrations  Official SDKs and server-side credentials Exposed keys or weak error handling  Integration is mocked or incomplete 
File storage  Private buckets and signed URLs Publicly accessible sensitive files  Files depend on local disk or database
Hosting and CI/CD  Meets scaling and compliance requirements Shared environments or missing deployment pipeline  Cannot migrate from builder-specific infrastructure 
Monitoring and analytics  Reliable events and alerts exist  Incomplete error tracking or visibility  No observability infrastructure exists 

What Lovable, Bolt, v0, Replit, Cursor and Claude Code Leave You With

The handoff requirements for a vibe coded app depend on the builder’s code structure, hosting model, database services, and repository integration.

Here is what I would review when transferring a project to a development team.

Builder  What you get  Where the code lives  What to check at handoff 
Lovable  React app with Lovable Cloud or integrated backend services  Lovable project with two-way Git sync  Moving from Lovable to production requires reviewing database policies, secrets, migrations, and deployment requirements.
Bolt  JavaScript-based app, Bolt Cloud hosting, Bolt Database or Supabase  Bolt project with GitHub integration  Review database permissions, credentials, deployment dependencies, and infrastructure portability 
v0  Next.js, React, TypeScript, Tailwind CSS, and shadcn/ui  v0 project with GitHub integration  Identify Vercel dependencies, environment variables, and server-side services 
Replit  Full-stack app with checkpoints and database support  Replit workspace with version control integration  Verify environment separation, backup recovery, production permissions, and deployment configuration 
Cursor  AI-assisted changes to your selected application stack  Your existing project and repository  Review generated modules, dependencies, testing coverage, and architecture consistency 
Claude Code  Agent-assisted implementation across your chosen stack  Your repository and development environment  Inspect code changes, permissions, automated tests, and release controls 

The capabilities above are described in the vendors’ official documentation: Lovable Git sync, Bolt, v0, Replit checkpoints, Cursor, and Claude Code.

Source code access alone does not guarantee a complete handoff. The team also needs control over production accounts, databases, storage, credentials, and deployment processes.

For more on AI-assisted development workflows, see our guide to vibe coding for mobile app development. For Apple-specific workflows, refer to building an iOS app with Claude Code.

Prototype to Production Timeline and Cost, Stage by Stage

The timeline and cost of taking an AI prototype to production depend on the condition of the existing application and how much engineering work can be preserved.

For an AI prototype to production engagement, AppVerticals uses preliminary scoping ranges to compare recovery options before defining the final project scope.

Stage  What happens  Estimated timeline  Estimated cost 
1. Audit  First-pass technical review and component decisions  1-2 weeks  $3,000-$8,000
2a. Stabilize  Access control and backend hardening  2-5 weeks  $8,000-$20,000
2b. Security cleanup  Dependency review and supply-chain remediation  1-3 weeks  $3,000-$10,000
3a. Targeted rebuild  Replace flagged components while preserving reusable work  4-10 weeks  $20,000-$60,000
3b. Full rebuild  Replace the existing application foundation  3-6+ months  $40,000-$150,000+
4. Test and launch  Critical-path testing, monitoring, staged deployment  Defined after discovery  Defined after discovery

Stabilization and security cleanup can run concurrently, while targeted rebuilding and full rebuilding represent alternative approaches. Testing begins during development and continues through deployment.

For comparison, a new lean MVP is estimated at $20,000-$40,000 over 8-12 weeks.

These are AppVerticals scoping estimates. A fixed quote follows discovery, once the technical requirements and implementation scope are confirmed.

What Investors Check in a Vibe-Coded MVP

Technical due diligence evaluates whether an application is secure, maintainable, and capable of supporting future development.

Reviewers examine the data model, backup and recovery processes, dependency licenses, test coverage, deployment documentation, and evidence of intellectual property ownership. They also assess whether another engineering team can maintain the application independently.

AppVerticals estimates comprehensive technical due diligence audits at $15,000-$40,000+ over 3-6 weeks, depending on scope.

Prototype to Production in Practice: Rescuing a Half-Built Freight Platform

AppVerticals helped Lulo Freight recover a partially developed freight management platform after a previous development partner left critical functionality incomplete.

The existing application had unfinished pricing logic, carrier workflows, and payment functionality. Our team assessed the architecture, established a shared data foundation, and prioritized load management and operational workflows.

According to our Lulo Freight case study, the completed platform delivered:

  • 60% faster quote decisions
  • 45% higher fleet utilization
  • 70% less manual freight coordination

Although Lulo Freight was not an AI-generated prototype, the project demonstrates how a structured technical assessment can recover valuable development work.

Choosing an MVP Development Company for a Vibe-Coded Rebuild

Choose an MVP development agency with experience in your builder’s technology stack, transparent scoping practices, and established testing and deployment processes.

The team should provide clear deliverables, a fixed quote after discovery, and a post-launch support plan.

Frequently Asked Questions

No. Moving an AI prototype to production does not always require a full rebuild. A rebuild is warranted when fundamental architectural or data-model problems make the existing application unsuitable for production. When the underlying structure is sound, developers can retain functional components and address specific weaknesses, reducing unnecessary development effort and cost.

Yes. Both platforms support GitHub-based workflows, allowing developers to work with the code outside the builder. However, teams need clear processes for code reviews, deployments, and database changes. Lovable may require additional deployment steps for externally modified backend functions or migrations, while Bolt projects require careful management of cloud and database dependencies.

Code ownership depends on the builder's terms, contractor agreements, and applicable intellectual property laws. Founders should maintain control of repositories and infrastructure accounts while securing appropriate IP assignments from developers. The U.S. Copyright Office explains that copyright protection for AI-assisted work depends on sufficient human authorship. Legal review is recommended before fundraising or acquisition discussions.

Yes. AI coding tools can support ongoing development when appropriate engineering safeguards are in place. Teams should require human review of pull requests, automated testing through CI pipelines, and restricted production access. AI agents should operate in isolated environments with test credentials, while production deployments follow an approved release process to maintain security and reliability.

A first-pass code review can identify weaknesses in access controls, secrets management, dependencies, and database architecture. The assessment helps determine which components can be retained, improved, or rebuilt before production.
