Vibe-Coded App Rescue & Security Hardening

Turn your AI-built prototype into production-ready software

No judgement: vibe-coding helped you prove an idea quickly. Real users, real data and ongoing change are a different job. Devy reviews what you have, hardens what is worth keeping, and tells you plainly when rebuilding is more economical than repair.

When this service fits

The prototype now carries responsibility it was never designed for

This work begins when a fast experiment becomes a product or internal tool that people, customer data or daily operations now depend on.

Built for

  1. 1A founder whose AI-assisted application now has real users, payment information or customer data.
  2. 2A business that commissioned an application which mostly works but fails unpredictably in day-to-day use.
  3. 3A team that suspects security or permission problems but cannot see where the risk sits.

Time to act when

  • The bug cannot be reproduced reliablyUsers hit failures that leave little useful evidence, so each fix starts with guesswork.
  • You are nervous about customer dataThe application stores real information, but authentication, permissions, backups or data handling have not been independently examined.
  • Every change breaks something elseThere is little test coverage or clear structure, so feature work increases uncertainty instead of product value.
What Devy delivers

A review and hardening plan tied to real risk

We prioritise the application behaviours that affect users, data and the team’s ability to change the product safely.

01

Codebase and architecture review

Trace how the application is structured, where responsibility sits and which parts create avoidable coupling or uncertainty.

02

Security vulnerability assessment

Examine authentication, permissions, data exposure and security-sensitive flows as engineering work, without claiming an unverified certification.

03

Reliability and performance

Identify reproducible failure modes, weak error handling and load or response issues relevant to the application’s actual use.

04

Bug remediation and test coverage

Fix prioritised defects and add tests around the workflows that must keep working.

Review path: from working demo to accountable recommendation
  1. 01Reproduce

    Observe the failures and important user journeys.

  2. 02Trace

    Follow code, data, permissions and deployment.

  3. 03Prioritise

    Separate immediate risk from maintainability work.

  4. 04Recommend

    Compare rescue effort with a rebuild path.

  5. 05Define

    Set the scope and acceptance criteria for the chosen route.
