Vibe-Code to Production | Replit, Lovable & AI-Built MVP Hardening

We take your AI-coded app to production while you keep vibe coding new features. Move from an AI-built MVP to a secure, live app.

Who Needs This:
Non-technical founders who built on Replit, Lovable, or Bolt and need to ship to real users
VCs and accelerators with portfolio companies on AI-built MVPs that aren't production-ready

Software Engineering Manager at MEV
With tools like Replit and Claude Code, a founder can build a prototype, test a concept with early users, or show investors a rough version of the feature.

Our job starts where the prototype needs to become real software. We review what was built, understand the logic through the code, stabilize the parts that are worth shipping, and flag the parts that are not safe yet. Sometimes we can clean up and deliver the feature. Sometimes we need to rebuild it because there are security, performance, authorization, or scalability issues.

AI can move the first version very fast, but production still needs engineering judgment. Someone has to know what to check, what to test, what to secure, and what should not go live. That is the difference between a working demo and software real users can rely on.
Built fast, stuck before launch?
We move your vibe-coded product from sandbox to real users. You keep experimenting, while we harden the app in parallel.
Signs Your Replit or Lovable MVP Needs Hardening:
[ 01/ ]

Fragile code: every new feature breaks the last one

[ 02/ ]

Stalled integrations: payments and auth never got finished

[ 03/ ]

Vibe coding security gaps: user data exposed, no access controls

[ 04/ ]

Untested under load: never validated with real user volume

[ 05/ ]

AI cost exposure: LLM calls with no spend caps or rate limits

The Parallel Track: How We Ship Vibe-Coded MVPs

Prototypes work until real users show up. We harden yours in a parallel production track, while you keep shipping.

[  You  ]
[  Us  ]
Keep vibe-coding in Replit
Run a parallel production track on AWS
Push through GitHub
Review via PR gate on a 1–2 day cycle
Ship new features
Set up replit.md, handle code freeze and migration discipline

Our Vibe Coding Hardening Services
[ 01/ ]

Production-readiness audit

We audit your Replit or Lovable codebase: architecture, security, AI integrations, database, deployment. You get a prioritized risk list and a rebuild-vs-refactor call.  Output: a roadmap to private beta.

[ 02/ ]

Stabilization & security hardening

We fix vibe coding security gaps in order of risk: authentication first, then secrets management, data integrity, observability, and performance. Each layer hardens without destabilizing the next.

[ 03/ ]

AI-integration hardening

AI integrations fail in production in ways prototypes never reveal. We add spend caps, rate limits, prompt-injection defenses, and webhook reliability across every LLM integration.

[ 04/ ]

Two-track founder collaboration

You keep shipping. We run a parallel production track and sync through a reviewed Git workflow. No pauses, no handoff chaos.

[ recent work/ ]

AI-powered learning platform
A non-technical founder built a complete AI product in Replit. It worked until the complexity outgrew the tool, and every new feature broke the last one.
AI-powered learning platform
Design adapted for confidentiality. Visuals are representative and differ from the final product under NDA.
We hardened it for real users without a rewrite and without pausing the build.
  • The founder kept shipping in Replit, while we ran a parallel production track on AWS.
  • Hardened 10 external integrations: LLM providers, AI video, document parsing, authorization, payments, and observability.
  • Spend caps and rate limits applied before the first real user.
  • Prompt-injection defenses across every AI integration.

Frequently asked questions

FAQ

Not necessarily. Most Replit and Lovable prototypes have large parts worth keeping. We start by identifying what works and what creates risk. Only the unstable or insecure parts get replaced. If a full rewrite is indeed the faster path, we'll communicate that early, during the audit.

Common with vibe-coded projects. Rapid prototypes mix experiments, temporary scripts, and unfinished integrations. We clean up the structure and separate responsibilities so the codebase can be safely extended.

Most Replit projects run on TypeScript, Node.js, React, or Python. We work with those regularly and move them to Replit production infrastructure on AWS: databases, APIs, third-party services, and Lovable app production environments included.

Yes. This is where most vibe-coded MVPs stall, and where AI MVP security gaps are most likely to appear. Payments, auth systems, mobile APIs, external platforms. We complete and stabilize those pieces.

Yes. Lovable and Replit prototypes rarely run on production-grade infrastructure. Before launch we set up cloud infrastructure, CI/CD pipelines, monitoring, and deployment processes.

It depends on the state of the prototype and the complexity of vibe coding security issues. Some projects need a few weeks of stabilization. Others need deeper architectural work before they are ready for real users.

We can start with a production-readiness audit. It gives both sides a clear picture of the work before committing to anything larger.
