Cline + MVP / Prototype

Built a mvp / prototype with Cline?
We'll make it production-ready.

You built a prototype with an AI tool and it works — on your machine, with your test data, for the happy path. Now you need real users to validate your idea. The goal isn't perfection — it's getting to a state where real people can use it safely and reliably. That means fixing the critical gaps without over-engineering.

MVP / Prototype challenges in Cline apps

Building a mvp / prototype with Cline is a great start — but these challenges need attention before launch.

Identifying what actually needs fixing

Not everything needs to be production-grade for an MVP. The challenge is knowing which shortcuts are acceptable (visual polish, advanced features) and which aren't (security, data loss, broken core flows). Our audit prioritizes fixes by impact.

Security minimum

Even an MVP handles user data. You need authentication that works, data isolated per user, no exposed secrets, and HTTPS. You don't need enterprise-grade security, but you need the basics done right.

Deployment

Your app runs locally but deploying it involves environment variables, domain configuration, SSL, and build optimization. First-time deployment is where most AI prototypes hit unexpected issues.

Error handling

When something goes wrong (and it will), your users should see a helpful message — not a white screen or a raw error. Basic error handling is the difference between 'this app is buggy' and 'something went wrong, please try again.'

Core flow reliability

Your main user flow (signup → core action → outcome) must work every time. Edge cases in secondary flows can wait, but the core path needs to be solid for your MVP to generate valid learnings.

What we check in your Cline mvp / prototype

Core user flow — does signup to core action work reliably?
Authentication — secure login, session handling, password reset
Data security — user data isolation, no exposed secrets
Deployment readiness — env vars, build configuration, domain setup
Error handling — graceful failures on the core path
Mobile experience — does the core flow work on mobile?
Performance — does the app load in under 3 seconds?

Common Cline issues we fix

Beyond mvp / prototype-specific issues, these are Cline patterns we commonly fix.

highSecurity

Unsupervised file modifications

Cline modifies multiple files autonomously. Without careful review, security-critical changes like auth configuration or API permissions can go unnoticed.

highSecurity

Dependency installation without audit

Cline installs npm packages autonomously without checking for known vulnerabilities, malicious packages, or unnecessary additions.

mediumBugs

Cascading changes across files

Cline's multi-file edits sometimes introduce bugs in files that weren't the focus of the change, causing regressions in unrelated features.

mediumBugs

Execution of generated scripts

Cline can execute terminal commands as part of its workflow. Generated scripts may have unintended side effects on your development environment.

Frequently asked questions

Can I build a mvp / prototype with Cline?

Cline is a great starting point for a mvp / prototype. It handles the initial scaffolding well, but mvp / prototype apps have specific requirements — identifying what actually needs fixing and security minimum — that need professional attention before launch.

What issues does Cline leave in mvp / prototype apps?

Common issues include: unsupervised file modifications, dependency installation without audit, cascading changes across files. For a mvp / prototype specifically, these issues are compounded by the need for identifying what actually needs fixing.

How do I make my Cline mvp / prototype production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Cline-built mvp / prototype apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.

How much does it cost to fix a Cline-built mvp / prototype?

Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger mvp / prototype projects, we provide a custom fixed quote after the audit — no hourly billing.
