Vibe Coding Audit | Investor-Ready Code | From $199
The Valletta Vibe Coding Audit is a fixed-fee senior-engineer review of an AI-built application. A real engineer reads your repo end to end, runs the app under realistic load, and delivers a written report with prioritized findings and concrete fixes. Pricing starts at $199. No retainer. No hourly billing. No automated scanner output dressed up as analysis.
What you get
- A written audit report — every finding scored on severity, exploitability, and fix effort. Plain English first, code references second.
- A prioritized remediation roadmap — what to fix this week, what to fix before raising, what to defer.
- A 30-minute walkthrough call — you ask the engineer who wrote the report anything about it.
- A re-audit credit — when you ship the fixes, we re-verify the critical findings at no extra cost.
What we look for
Vibe-coded apps fail in predictable places. The audit checks every one of them:
- Authentication and session handling — missing CSRF, broken JWT, session cookies without expiry, social-login flows that trust the client.
- Authorization — IDOR vulnerabilities, missing role checks, admin endpoints exposed to anonymous users.
- Secrets management — hardcoded API keys, environment files shipped to the client bundle, credentials in git history.
- Input validation and injection — SQL injection, command injection, prompt injection, unvalidated file uploads.
- Rate limiting and abuse — unbounded endpoints (especially LLM-backed ones), missing email-verification throttling.
- Data exposure — verbose error messages, debug routes left in production, public S3 buckets, leaked tokens in client-side logs.
- Dependency hygiene — outdated packages with known CVEs, abandoned libraries, transitive vulnerabilities.
- Production readiness — observability, error tracking, backup strategy, deployment rollback, basic monitoring.
The full checklist runs to about 80 items. We adapt the depth to your stack — a Lovable app gets a different lens than a Cursor-built Next.js project. For more on how tool choice shapes the audit, see our breakdown of vibe coding tools and what each one defaults to.
How we're different from the alternatives
Vs. automated code review tools (CodeRabbit, Greptile, Graphite)
Automated tools catch syntax-level issues and well-known patterns. They miss the things that actually sink a fundraise: business-logic bugs, broken authorization, race conditions, "works but is wrong" code paths that pass every linter. A scanner that has never seen your app cannot reason about whether a permissions check is in the right place. A senior engineer can. For the practical view, see our guide on how to audit a vibe-coded app before it goes live — what a real review covers versus what scanners miss.
Vs. hourly consultants
Hourly billing has the wrong incentive: the longer the audit, the more revenue. Our fixed fee aligns us with you. The audit takes as long as it takes; the bill doesn't change.
Vs. "vibe coding agency" retainers
Retainer-based agencies sell ongoing work because that's the only model that works for them. If you just need to know whether your app is safe to ship — and what to fix if it isn't — a one-time audit is the right tool. We'd rather you ship and not need us again than charge you to babysit code that's already fine.
What an audit costs
| Tier | App size | Price | Turnaround |
|---|---|---|---|
| Starter | Single-feature MVP, < 5,000 LOC | From $199 | 3 business days |
| Standard | Multi-feature SaaS, 5,000–25,000 LOC | From $799 | 5 business days |
| Investor-ready | Pre-raise diligence package, any size | From $1,499 | 7 business days |
The Investor-ready tier is what most founders book before a term sheet. It includes the full audit plus a buyer-facing summary document you can hand to a diligence partner — written for non-technical readers but defensible under technical scrutiny.
How the process works
- Request — submit your repo URL, stack, and what the app does. 5-minute form.
- Scope — we confirm the tier and price within one business day.
- Read — a senior engineer reads your code, runs the app, exercises the auth flow, and tests edge cases.
- Report — you get a written report and a 30-minute walkthrough call.
- Fix — you remediate. We answer questions over email at no extra charge.
- Re-verify — when you're done, we re-check the critical findings.
Who this is for
- Founders who built with Cursor, Lovable, Bolt.new, Replit, or v0 and want a sanity check before launch or fundraise.
- Teams who took a vibe-coded prototype to paying customers and now need to know what to harden.
- Investors running technical diligence on a pre-seed or seed company.
- Anyone whose app handles PII, payments, or anything regulated and was built primarily with AI tools.
If you're not sure your app qualifies, the vibe coding explainer covers the borderline cases. For the security angle specifically, the post on vibe coding security risks walks through the categories we check most.
What you don't get
To be honest about scope:
- We don't fix code for you — the audit is the diagnosis, not the surgery. (If you want hands-on remediation afterward, we can refer.)
- We don't do penetration testing — the audit is white-box review, not adversarial testing. Pen tests come after.
- We don't do compliance certification — SOC 2, HIPAA, PCI all require certified auditors. We'll tell you what to fix to be ready for one.
- We don't audit infrastructure-as-code in depth — we touch on it, but a dedicated cloud review is a separate engagement.

Frequently asked questions
How long does a Vibe Coding Audit take?
Starter tier reports go out within 3 business days of the kickoff call. Standard is 5 days, Investor-ready is 7. Rush turnaround is available for an additional fee when calendars allow.
Will you sign an NDA?
Yes. We sign mutual NDAs as standard. Send yours or use ours — either works.
What stacks do you cover?
Anything that ships on the web. Common: Next.js, React, Node, Python (FastAPI/Django), Supabase, Postgres, Firebase, Vercel, Railway. If your stack is unusual, ask — we'll either take it or refer you to someone who specializes in it.
Can I get just the security part?
Yes. The Starter tier can be scoped to security-only at a reduced fee for very small apps. For most projects the full audit is the better value — the things that get caught in "non-security" review (broken authorization, missing rate limits) are usually the things investors flag first.
Do you offer a fixed-fee remediation package?
Not as a default service. After the audit, founders typically fix the findings themselves with a junior engineer or contractor. If you need senior help on the fix, we can scope it as a separate engagement.
