How Varyence helped a hospitality startup assess a Lovable-built marketplace MVP, uncover critical launch-blocking security gaps, scalability issues, functionality concerns, and define a safer path to launch.
A UK-based hospitality startup had a clear vision: a marketplace connecting chefs with food lovers seeking personalized culinary experiences. To validate the concept quickly, the team built an early-stage MVP using Lovable, a popular AI-powered development tool.
Like many apps built with modern vibe coding tools, the product looked polished and functional. Key user flows were working, investor demos had gone well, and the team was preparing for a launch. From both the outside and the inside, the product appeared ready.
But beneath the surface there were critical architectural, security, functional, and operational gaps.
The startup faced one pressing question:
“Is this application truly ready for real users or only as a prototype?”
The client engaged Varyence to perform a focused Vibe Coding Security Assessment and production-readiness review.
Our evaluation covered issues around:
The assessment revealed that while the frontend was polished and functional for demos, critical backend vulnerabilities existed, including:
Such vulnerabilities are common in AI-generated and vibe-coded applications and rarely visible without expert review.
Had the team launched publicly, user data could have been comprised from day one.
Rather than risk a public release, Varyence helped the client reframe the MVP as a prototype suitable for internal demos, investor presentations, and controlled validation.
This approach provided clear risk visibility, realistic deployment guidance, and a roadmap to production readiness without a full rewrite.
Varyence performed a security, scalability, and production-readiness assessment for the Lovable MVP, a marketplace-style web application connecting chefs and customers through profiles, menus, ordering workflows, and planned payment functionality. We found the platform was an early-stage prototype, not production-ready. The UI worked well for demos, but major backend and operational issues made it unsafe to launch.
The startup needed a clear-eyed, third-party review.
Specifically, they needed to:
We utilize industry best practices & leverage our global delivery capabilities to ensure successful business outcomes for our customers.
Varyence assessed the platform before a launch occurred or any data was exposed. The client engaged Varyence to perform a focused Vibe Coding Security & Production Readiness Assessment before proceeding with the public launch. Our team reviewed the platform across five dimensions: security, scalability, usability, operational readiness, and core business functionality.
What the assessment delivered:
A full security review uncovered nine significant issues across the platform:
| WHAT WE FOUND | SEVERITY |
|---|---|
| Frontend-only authentication; login could be bypassed entirely | Critical |
| Login credentials hardcoded directly in the source code | Critical |
| No server-side session management; no real user identity enforcement | Critical |
| No admin or governance layer; no way to manage or moderate the platform | High |
| Orders disappeared after confirmation; broken order lifecycle | High |
| Payment processing not implemented; transaction logic missing entirely | High |
| Profiles and menus failed to save reliably | High |
| Payment method data did not persist between sessions | High |
| No backend enforcement; all logic ran client-side, which could be easily manipulated by hackers if released | High |
Rather than recommending a rebuild from scratch, Varyence helped the client properly position the product as a working prototype and delivered a targeted path forward to extend, refine, and remediate the Lovable prototype.
This allowed the client to continue using the platform for investor conversations, stakeholder demos, and controlled validation while clearly understanding what needed to be hardened before go-live.
Varyence handled the technical review and strategic guidance across CTO leadership, solution architecture review, cybersecurity assessment, production readiness analysis, functional gap analysis, scalability assessment, risk prioritization and remediation planning
