When a prototype needs an engineering review
A preview can demonstrate a concept while still relying on demo data, permissive access rules or an incomplete integration. Bring the application for review when you cannot explain how accounts are separated, how payments are confirmed or how another developer can deploy it.
This service is useful for founders with a working prototype, an exported repository or an existing early release. It is also useful when the next feature has become difficult to add because the data model and application structure are unclear.
- Sign-in works, but roles and data access have not been checked.
- Payments or external APIs work only in a happy-path demo.
- The product cannot be reproduced outside its preview environment.
- A generated feature broke an existing workflow.
- You need a scoped plan before accepting real customer data.
What the review can cover
Agree the assessment boundaries before work begins. We inspect the critical workflow and the parts of the application needed to support it. Security-sensitive or highly specialized systems may require an additional specialist review; this is development assessment, not a compliance certification.
| Area | Review questions | Useful output |
|---|---|---|
| Code and setup | Can the app be reproduced and maintained? | Setup findings and dependency issues |
| Accounts and permissions | Does the backend enforce the intended roles? | Access-control issues with reproducible cases |
| Data | Are ownership, migrations and recovery clear? | Data risks and proposed corrections |
| Integrations | What happens on failure or duplicate delivery? | Failure cases and repair scope |
| Deployment | Who owns production and can roll it back? | Launch dependencies and handoff tasks |
A prioritized repair or rebuild plan
An agreed assessment should leave a written issue list with evidence, release blockers, later improvements and unresolved questions. We discuss which parts can be retained, which need repair and which are cheaper or safer to replace.
The implementation proposal separates the audit findings from the work needed to resolve them. It names included features, acceptance tests, dependencies, deployment and handoff. The assessment and build scope are agreed before implementation; completing a review is not an automatic production approval.
From repository access to a release decision
First, share the intended user journey, working preview, known issues and the tool used to create the prototype. Arrange appropriate repository and test-environment access after scoping. Do not send production credentials or customer records through the enquiry form.
Second, reproduce the application and inspect the agreed workflow using synthetic accounts and data. Third, review the findings together and decide the repair or rebuild scope. Finally, implement the agreed work, test acceptance criteria and prepare the production handoff.
- Define what launch-ready means for this release.
- Check the actual backend and integrations, not only screenshots.
- Retain useful implementation where it meets the requirements.
- Reserve time for testing, recovery and documentation.
Relevant product work you can inspect
Kraydl's public portfolio includes Rsyntra's AI receptionist and CRM, Propeny's restaurant phone-ordering platform and CloneX AI's mobile avatar product. Use these pages to discuss application workflows and delivery capabilities.
These projects are not presented as audited vibe-coded rebuilds, and their results or budgets should not be assumed for your prototype. The review recommendation comes from the application we inspect.
Scope the assessment and implementation separately
The review fee and timeline depend on the repository, platforms, integrations and assessment depth. We confirm them after discussing the application. A focused implementation may fit Kraydl's $4,000 sprint; an agreed first release may fit the $12,000 Complete MVP Package. Neither is a blanket audit or rebuild price.
A multi-client app, sensitive data, migration or several integrations can require a custom proposal. Hosting, third-party services and ongoing maintenance are scoped separately. Send the primary workflow and known blockers so the first conversation can identify the appropriate next step.

FAQ
Do you automatically rebuild every AI-generated app?
No. The assessment identifies what can be retained, repaired or replaced based on the actual code and requirements. A rewrite is one possible outcome, not the default recommendation.
What do I need to share initially?
Share the intended workflow, tool used, working preview, supported platforms and known problems. Arrange repository access after scoping; keep credentials and personal customer data out of the enquiry form.
Is the review a security certification?
No. It is an agreed software assessment and release-planning engagement. Specialist security or compliance assurance requires an appropriate separate scope.
Can you help with deployment and handoff?
Yes, when included in the agreed implementation scope. Confirm production account ownership, environment configuration, testing, recovery instructions and support responsibilities in the proposal.
Build the right version first.
Bring Kraydl the workflow, launch goal, risk constraints, and timeline. We will help turn it into a scoped product plan and a build path founders can actually use.
