Your Vibe‑Coded SaaS Is One Step Away from Revenue
You hacked together a working product with Cursor, Claude, Copilot, Gemini and friends. Customers are interested, demos are working, but you don't quite trust the auth, billing, or AI bits enough to charge money yet. We come in right at that moment to turn a vibe-coded app into something you can safely put a price tag on.
What We Actually Do in a Code Audit
This is not a generic scanner report. We pull your repo, run the app, follow real user journeys, and then read the code like a staff engineer who cares about your first 100–1,000 paying customers, not just green test badges.
Security & Risk
We treat your vibe-coded app like a real production system: logins, roles, payments, and AI calls are all checked for places where revenue or data could leak.
- Auth, roles & multi-tenant boundaries
- Payments, webhooks & subscription logic (Stripe, Paddle, etc.)
- API keys, secrets & environment configuration
- Input validation and data sanitisation across forms and APIs
- SaaS- and AI-specific OWASP-style vulnerability sweep
Reliability & Edge Cases
Most vibe-coded SaaS apps work perfectly in the demo. We break the happy paths on purpose so you don't do it live in front of your first 100 paying customers.
- Onboarding, invite and password reset flows under stress
- Billing edge cases: trial expiry, failed payments, downgrades
- Error handling, retries, and timeouts around external APIs/LLMs
- Prompt, RAG and tool output guardrails for weird user input
- Data migrations and background jobs that might quietly fail
Architecture & Performance
We untangle AI-generated spaghetti, dead files, and one-off hacks so you end up with something your future team (or future you) can actually maintain.
- File, module and feature structure clean‑up for your repo
- Database query and API performance review (N+1s, missing indexes)
- Logging, metrics and basic observability recommendations
- CI/CD and deployment sanity checks (Vercel, Render, Fly, etc.)
- Best practices so AI tools stop re-breaking the same areas
More Than Just a Code Audit
A code audit is just the beginning. Many projects require a deeper evaluation to ensure scalability, security, and long-term success. That's why we offer additional assessments tailored to different business needs.
Evaluate your system's architecture to identify inefficiencies, scalability limitations, and security risks. Our experts provide actionable recommendations to future-proof your infrastructure.
Get a comprehensive analysis of your tech stack, including performance, security, and best practices. Ensure your technology choices align with your business goals and industry standards.
Designed for startups, this audit assesses both your technology and development processes. We help you build a scalable foundation, avoid technical debt, and prepare for future growth.

Our 4 Pillars of IT Due Diligence
Product Roadmap: Gain a comprehensive understanding of how your target or acquisition aligns with your current and future business and audience needs. This involves tracking, planning new features, conducting a UI/UX review, and more.
Technology Assessment: Obtain valuable insights through a thorough analysis, including architecture scalability, team readiness, current security, compliance levels, and identification of embedded issues and required fixes.
Economies of Scale: We'll guide you to identify quick wins, like consolidating similar functionalities across platforms (e.g., payment gateways, access control, venue mapping/seat selection).
Skills and Processes Review: Depending on the merger or acquisition, we'll help you identify key contributors for ongoing product development and long-term success. Understand internal processes like sprint planning and QA testing in depth.
We Speak Your Stack (AI or Not)
Most of our clients run the same pattern: a Next.js / React front end, a Node or Python backend, Postgres or Supabase, Stripe for billing — with a layer of AI (OpenAI, Anthropic, Gemini, custom RAG) sprinkled in on top.
We don't care whether the rough edges came from AI tools or late nights, we help you turn that messy, vibe-coded SaaS into a clean, auditable product that investors, security teams and paying customers can trust.
A Clear Picture of What Your Software Can Become
Don't let small issues compound, get a solid read on what you're building on. Your codebase powers your business. It carries you, your stakeholders, and your customers. Whether you need to confirm your product is running cleanly, can handle new features or heavier load, or you want to uncover security gaps before they bite, our code audit gives you the clarity to move ahead with conviction. In our source code reviews, we look at the following areas.
Bugs get harder to untangle once they calcify into years of workarounds and one-off patches. We give you an honest read on what's actually covered by tests and how to grow that coverage.
Breaches keep climbing and the tolerance for slipping up keeps shrinking. We help you spot the red flags early by stress-testing your flows before anyone malicious gets there first.
Silent inefficiencies can drag your product and the worst part, your customers, right down with it. Slow response times cost trust, so we surface the weak paths before users feel them.
Your own code and the dependencies you rely on are always shifting underneath you. Written with steady upkeep in mind, even a small refactor won't balloon into a painful rewrite later.
When regulations apply to your industry, vibes don't cut it. We verify whether your code genuinely meets the rules you've committed to, rather than assuming it already does.
Make sure your software is ready to grow with demand. We help you shore up the soft spots so your product doesn't wobble at the exact moment things finally take off, letting you build a sturdy foundation to grow on.
Project Code Audit Deliverables
After we conduct our code audit, we present clients with a detailed report of our findings, potential code issues, and recommendations. The report includes both critical and non-critical issues as well as expert guidance on managing issues based on our client's priorities. When necessary, we can involve a project manager in the software auditing process so you can receive detailed explanations of individual issues.
Depending on the project requirements, the report can include:
- Software code analysis
- Architecture analysis - including strengths and weaknesses
- Security audit
- Automation tests audit and pentest review
- Design review
- Software audit checklist
- Document findings from each phase of the assessment
- Recommendations for improving the assessed quality attributes
How a VibeAudits Code Audit Unfolds
From the first discovery call to a clean, prioritised fix list, here's exactly what to expect when we audit your vibe-coded SaaS.
Step 01
Step 01
Discovery Call, NDA & Scope
A 60-minute call to understand your product, stack and the revenue-critical flows you're most worried about before launch. We sign a mutual NDA up front so you can share freely.
- Mutual NDA signed before any code or credentials are shared
- Walk through the app, user journeys and business model
- Map the stack: framework, DB, auth, payments, AI providers
- Agree on priorities, what must be solid before charging money
Step 02
Step 02
Repo & Stack Deep Dive
We pull the repo, run the app locally and read the code like a staff engineer who cares about your first 100–1,000 paying customers.
- Clone, build and exercise real user journeys end-to-end
- Trace AI-generated patterns, dead files and one-off hacks
- Flag architectural soft spots that will bite as you grow
Step 03
Step 03
Security & Risk Sweep
The part founders lose sleep over: auth boundaries, payments, secrets and AI surfaces are stress-tested against how real attackers behave.
- Auth, roles and multi-tenant isolation checks
- Stripe / Paddle webhooks, trial logic and subscription edges
- API keys, env config and AI/RAG prompt-injection guardrails
Step 04
Step 04
Reliability & Performance
We break the happy paths on purpose so your first paying customers don't do it live. Database, background jobs and external APIs all get pressure-tested.
- Onboarding, invite and password-reset flows under stress
- N+1 queries, missing indexes and slow endpoints
- Retries, timeouts and failure modes around LLM calls
Step 05

- Must-fix-before-launch items with reproduction steps
- Concrete refactor suggestions your team or AI tools can ship
- Notes on observability, CI/CD and infra gaps
Step 06
Step 06
Fix Support & Re-check
Optional hands-on help to ship the fixes, plus a follow-up pass so the same issues don't quietly reappear the next time AI tools touch the repo.
- Pair on the highest-risk fixes or ship them for you
- Re-verify the critical findings once patches land
- Leave behind guardrails so AI doesn't re-break the same areas
