Your Vibe-Coded MVP Looks Production-Ready. Our Audit Says Otherwise.

Vibe coding ships fast — but "looks done" isn't "safe to scale." Here's what a Production Readiness Audit uncovers before your first enterprise customer does.

TL;DR

Vibe coding is a superpower for validation. In a weekend you have a product that demos beautifully, users can sign up, and someone is willing to pay. That is real progress — do not let anyone tell you otherwise.

The trap comes next. "Looks shipped" and "safe to scale" are two very different things, and the gap between them is usually invisible until a bigger customer, an investor, or a regulator starts asking questions. A Production Readiness Audit tells you, in plain language, which of five gaps will bite you first — and what it will cost to close them before they cost you a deal.

The vibe-coded product paradox

Your product looks finished. The landing page converts. The onboarding is smooth. Users log in, click around, and stay. First customers pay. The team is proud, and they should be.

Then a bigger customer shows up. They want SSO. They send a 120-question security questionnaire. Their legal team asks for a DPA and wants to know where data is stored. Their procurement team asks whether you have SOC 2 in progress. Suddenly your beautiful product feels like it is standing on stilts. Founders often describe this moment the same way: "Everything works. I just can''t prove it works safely."

That is the vibe-coded product paradox. The features are real. The revenue is real. What is missing is everything a serious buyer assumes is already there — and until you know exactly what is missing, you cannot price the fix, sequence it, or promise a date.

What a Production Readiness Audit actually is

A Production Readiness Audit is a time-boxed, read-only assessment of your product against the standards a paying B2B or enterprise customer will hold you to. At co.brick we run it in one to two weeks, depending on codebase size. We look at your repository, your cloud console, your database, your auth flow, your CI/CD (if any), and your operational runbooks (if any).

We do not touch production. We do not pitch a rewrite. We deliver a single document: a prioritized list of findings, each with a severity, an effort estimate, and a plain-language explanation of what it means for your business — plus a shortlist of what to fix before your next enterprise conversation.

Below are the five categories where vibe-coded MVPs consistently fail the audit.

Finding #1 — RBAC that isn''t really RBAC

Role-based access control is the rule that says "this person is allowed to do this thing." It sounds boring until it fails, at which point it becomes the incident report on your homepage.

In a healthy system, every sensitive action is checked on the server, against a role that is stored separately from the user record, and enforced at the database layer. In a vibe-coded MVP, we typically find something very different:

• A boolean isAdmin field sitting on the user row, editable by anyone who can update their own profile.
• Role checks that happen only in the frontend — hiding a button is not the same as blocking the request behind it.
• A single "admin" role that means everything, so every internal user has the keys to every customer''s data.
• No audit trail of who did what, which means you cannot answer a customer''s "who accessed my data?" question.

The founder-visible symptom is uncomfortable. A support engineer opens a ticket and, in the course of "helping," ends up looking at another customer''s data — not because they wanted to, but because the tooling made it the easiest path. In the audit report this always lands as a critical finding, because it is the single fastest way for a vibe-coded product to end up in a breach notification email.

Finding #2 — Multi-tenancy that leaks

If you sell to more than one company, you are running a multi-tenant system, whether you designed it that way or not. Every row in your database belongs to a tenant, and the entire product depends on never — ever — showing one tenant''s data to another.

Vibe-coded products almost never enforce this at the layer that matters. Common patterns we see:

• Shared tables with a tenant_id column that is filtered only in the UI or in a single query helper — miss it once and you leak.
• No row-level security in the database, so anyone who obtains a valid auth token can read across tenants with a hand-crafted request.
• Admin tools and internal dashboards that query across tenants by design, with no isolation between them.
• Background jobs and webhooks that run without a tenant context, so a bug in one tenant''s data can silently corrupt another''s.

This is the finding that most often kills enterprise deals. A serious buyer''s security team does not want to hear "we filter it in the query." They want to hear "the database itself refuses to return another tenant''s row." Closing that gap early is cheaper than closing it under contract pressure with a signed LOI on the table.

Finding #3 — SaaS foundations missing

Beyond auth and tenancy, there is a short list of things every serious SaaS product is expected to have. Vibe-coded MVPs skip most of them, because they do not show up in the demo:

• Audit log. An immutable record of who did what, when. Required by most compliance frameworks and by any customer with a security team.
• Per-tenant rate limits. Without them, one noisy customer degrades the product for everyone else, and one malicious request can take you offline.
• Billing and entitlements in sync. Vibe-coded products often store subscription state in one place (Stripe) and feature access in another (a hand-coded config), and the two drift. Customers pay for features they cannot use, or use features they stopped paying for.
• Backup and restore that has actually been tested. A backup you have never restored is a hope, not a plan. The audit asks for a timestamp of the last successful restore drill.
• A defined data retention and deletion policy. GDPR and every enterprise DPA will ask for one.

None of these are glamorous. All of them will appear on the first serious security questionnaire you receive.

Finding #4 — Secrets, keys and supply chain

The fastest way to lose control of your product is to lose control of a credential. Vibe-coded MVPs have a lot of them, and they tend to live in the wrong places:

• API keys pasted into the frontend bundle, visible to anyone who opens the browser''s network tab.
• Service role keys and database URLs committed to the repository, or shared over chat during a late-night debugging session.
• Third-party integrations authenticated with a long-lived personal token belonging to whoever set it up first.
• No rotation policy, so the day someone leaves the team, nobody knows which keys they still hold.
• Dependencies pulled with floating versions, no lockfile discipline, no automated dependency scanning, and no alerting when a new CVE lands on something you use.

The audit inventories every credential and every third-party dependency, flags what is exposed, and gives you a rotation and scanning plan you can hand to one engineer for one week.

Finding #5 — No tests, no CI/CD, no safe way to ship

The final category is the one founders resist most, because it feels like process overhead. It is not. It is the difference between shipping a fix in twenty minutes and shipping a fix in three days with your heart in your throat.

What we consistently find in vibe-coded MVPs:

• No unit tests, no integration tests, no end-to-end tests. Every change is verified by clicking around and hoping.
• No continuous integration — nothing runs automatically when code is pushed, so regressions land in production and are noticed by customers.
• Deploys that happen from a laptop, sometimes over coffee-shop Wi-Fi, with no record of what shipped when.
• No staging environment that mirrors production, so the first time a change meets real data is when a customer hits it.
• No rollback plan beyond "revert the commit and hope."

You do not need Google-scale infrastructure to fix this. You need a test suite that covers your critical paths, a CI pipeline that runs on every push, a staging environment that behaves like production, and a one-command deploy with a one-command rollback. That is a week of focused work for a senior engineer, and it changes how the whole team sleeps.

What the audit report looks like

Every finding lands in the report with four things attached: a severity (critical, high, medium, low), an effort estimate (hours or days, not story points), a plain-language explanation of the business risk, and a concrete first fix. At the front of the report you get two shortlists:

• Fix before your next enterprise call. The handful of items that will fail a real security review.
• Safe to scale checklist. The full set of things that need to be true before you can confidently 10x your customer count.

The report is written for founders first and engineers second. You should be able to read it, understand it, and use it in a board meeting — not just forward it to your tech lead.

When to book it

The best time to run a Production Readiness Audit is before you need one. In practice, that means: before your next fundraise, before the first security questionnaire lands in your inbox, before your first enterprise pilot, or right now if you already have real customer data flowing through a system nobody has ever audited.

Vibe coding got you to a product people want. A short, honest audit is what gets you to a product people trust.
