seniorgrade // production-readiness audit reviewed by a human, not a scanner read-only access report typically ≤ 48h

Your AI wrote the code. Should the same AI
be the one to check it?

It built the problem in the first place. seniorgrade is a real senior engineer who reads your actual code and tells you — in plain English — whether it's safe to put real users and real data behind it.

Read-only — we can't change, push or delete anything. Your code is never executed, and deleted after the audit.

Built to review apps from the tools founders actually use

01The doubt

You built something with Lovable, Bolt, Cursor or Claude. It runs. It looks finished. You've been using it yourself, maybe with a few friends. Now you want real users and real data behind it — and the doubt hits.

  • ? Is it actually secure, or just untested?
  • ? Will the architecture hold under real load?
  • ? Is there an API key sitting exposed somewhere?
  • ? Can one tenant read another tenant's data?

The AI that built it won't tell you honestly. It built the problem in the first place.

02Why a human

A scanner tells you what every app is missing. A human tells you what will kill yours.

Same green checkmarks. Completely different answer.

○ Free AI scanner

Pattern-matches and guesses

Checks what's visible from the outside. Built by the same kind of AI that created your vulnerabilities.

  • Generic warnings that fit any app
  • Doesn't understand your code — it pattern-matches
  • A 200-item checklist, no priority
  • Misses the bugs where everything looks green
  • Leaves you alone with the output
vs
● A senior engineer

Reads your actual code

Understands your context — auth, data model, multi-tenancy, payment logic — and the things only a human catches.

  • Finds the bug where the backend is wide open
  • Understands what your code is actually trying to do
  • Tells you what breaks before launch — and in what order
  • Plain English, critical risks first
  • And we can fix it for you afterwards

You'd never merge an intern's pull request without reading it. "The AI wrote it" is that same unread code — and deploy-first, think-never is exactly how a green checkmark becomes a data leak.

03What you get

A report you can act on. Not a 200-item dump.

Just the findings that matter — a clear risk read, ordered by what gets you in trouble first. For each one: how dangerous it is, and how much work the fix is.

  • Prioritized, in plain English

    Critical risks first. Read it top-to-bottom and stop when you've run out of time — the important things are already at the top.

  • The classic vibe-coding killers

    Exposed secrets, broken auth, an unlocked database, missing tenant isolation, scaling traps.

  • A 15-minute call to walk through it

    We go through the findings together so you know exactly what to do — and in what order.

04What we check

Six things we check before you put real users behind it.

A focused production-readiness review — a fast senior read of the biggest launch risks in each area, prioritized. Not a full penetration test or an exhaustive enterprise audit; the things that actually break first.

01

Security

Exposed secrets, broken auth, unprotected endpoints, injection risks. The things that turn into an incident on day one.

02

Data & multi-tenancy

Database access rules, row-level security, tenant isolation — can one customer reach another's data?

03

Scalability

Where it falls over under real load: naive queries, missing indexes, N+1s, no caching, blocking operations.

04

Cloud & infrastructure

How it's deployed and configured — environment separation, secrets management, backups, what happens when something fails.

05

CI/CD & deployment

How code gets to production: pipeline, staging vs. prod, rollback, whether a bad deploy can be undone safely.

06

Does it do what you intended?

A check against what you set out to build — gaps between the requirements in your head and what the code actually does.

05In practice

What a real read turns up.

Representative examples of what a senior engineer finds in vibe-coded apps — the kind of issues, prioritized. Illustrative, not specific clients; real anonymized case studies follow as audits ship.

Next.js + Supabase · B2B SaaS · pre-launch

The database was open to every user.

Illustrative example
  • CriticalRow-level security disabled — any logged-in user could read every table.
  • CriticalStripe secret key shipped in the client bundle.
  • Warning/admin reachable with no session check.

Three blockers fixed before launch — relaunched safely within a week.

Bolt + Firebase · two-sided marketplace · ~200 users

One seller could read another's orders.

Illustrative example
  • CriticalNo tenant isolation — order queries trusted a client-supplied org id.
  • WarningFirebase rules still in test mode (allow read: if true).

Tenant boundary enforced server-side — the data-leak path was closed.

Cursor + Node / Postgres · AI writing tool · scaling

It could have run up a four-figure bill overnight.

Illustrative example
  • CriticalNo rate limiting on the LLM endpoint — open to abuse and runaway cost.
  • WarningN+1 query that fell over past ~1,000 rows.
  • MinorSecrets committed in a .env file.

Rate limits added and the query indexed — ready for the launch spike.

Shashank

Senior Engineer · reviews every audit personally

The name promises an experienced human — so here he is. A computer-science-trained engineer who works hands-on with the same AI tools your app was built with, Shashank reviews the security- and production-critical parts of your code: auth flows, data model, payment logic, the architecture decisions your AI made silently. He's the one who finds the bug where everything looks green and your backend is still wide open. Not a scanner, not a junior, not a queue — one experienced engineer, start to finish.

08Your code is safe

Handing over your code is the scary part. Here's exactly what happens to it.

Read-only access

We can't change, push or delete anything. We only read.

Never executed

Your code is read for the review only — it's never run on our machines.

Deleted after the audit

Once the report is delivered, your code is removed from our side.

No reselling, no sharing

Your code is used for your review. Never shared with third parties.

09What founders say

Founders and builders, after the read.

46 reviews from people who had a senior engineer read their AI-built app before launch.

Portrait of Alex Morgan Alex Morgan Solo SaaS Builder · United States
Seniorgrade helped me catch issues I would have missed because the app looked finished from the outside. The main finding was that one internal admin route still had weak protection. The report was specific, prioritized, and easy to hand over to my developer.
Portrait of Daniel Kim Daniel Kim AI Product Builder · South Korea
The review felt different from an automated scanner. It looked at the actual logic of the app, not just surface-level vulnerabilities. Seniorgrade found an endpoint that could become expensive under abuse because rate limiting was missing.
Portrait of Noah Jensen Noah Jensen Agency Owner · Denmark
We had built a client portal quickly and needed someone to check whether it was safe enough to hand over. Seniorgrade found gaps in tenant separation and file access. The audit saved us from launching something that looked polished but was not yet production-ready.
Portrait of Priya Nair Priya Nair RevOps Manager · India
We had an internal sales tool that stored customer and lead data. Seniorgrade found permission issues that could have allowed the wrong users to access records. That was a serious finding and exactly why we wanted a review.
Portrait of Fatima Al-Hassan Fatima Al-Hassan Product Owner · UAE
The best part was the prioritization. The report separated urgent launch blockers from improvements that could wait. That helped us avoid wasting time polishing minor things while a real authorization issue still existed.
Portrait of Maximilian Bauer Maximilian Bauer AI Startup Operator · Germany
Seniorgrade identified several small architecture problems and one serious security concern. The report changed our launch plan, but in a productive way. We fixed the main issue and launched with more confidence.
Portrait of Hannah Müller Hannah Müller Startup Advisor · Austria
I recommended Seniorgrade to a team that had built an MVP almost entirely with AI. The audit gave them a sober view of what was actually ready and what was still risky. It was useful because the report translated technical issues into business risk.
Portrait of Ravi Desai Ravi Desai Data Analyst · United States
I had created a dashboard that connected to several data sources. Seniorgrade found a weak access pattern and suggested a cleaner way to handle credentials. That prevented a potentially serious data exposure.

10Why us

We don't just review production apps. We run them.

seniorgrade isn't a consultancy that's never shipped. We build and operate our own products — with the same AI tools you use — so we read your code the way we read our own.

We ship our own products

Real software in production, with real users and real data — like leadscraper.de. We run into the same production realities this report flags, and fix them.

Vibe-coded to production-ready

Getting AI-built apps to production is a craft we've turned into a repeatable, modern method on our own projects — and that's exactly what your audit applies.

Made in Germany

A real company you can reach

Operated by Deimann Com GmbH in Hamburg — German engineering standards, GDPR-aware, and real humans behind every audit, not a faceless queue.

11What's at stake

Skip the read, and the bill comes later — with interest.

"It works" buys you a demo. It doesn't buy you a business. Here's what unreviewed vibe-coded software actually costs once real users and real data show up.

It buckles under real users

Solid for ten. At ten thousand — on launch day, when everyone's watching — it falls over.

A data leak gets expensive

Exposed customer data isn't just embarrassing. Under GDPR, a breach can mean fines into the millions.

It tanks your valuation

Raise or sell, and technical due diligence opens the hood. Security holes and tangled code cut your price — or kill the deal.

You rebuild from zero

Unreviewed shortcuts compound. One day the codebase is too tangled to extend, and you start over — losing months.

Bugs breed bugs

Every unreviewed fix spawns three more. Soon you're all firefighting and no shipping.

A bill you never approved

An open, un-rate-limited endpoint is an invitation. A bored script can run your cloud or AI costs into four figures overnight — on your card.

Shipping vibe-coded software without a senior read is building on quicksand — it looks solid, right up until you put real weight on it.

12The new way

The way you build changed. Your safety net should too.

Founders, PMs — even testers — ship code directly now: fast, AI-assisted, no tickets. It dropped the one thing the old way always had: a senior read before production. Here's the modern setup that puts it back — without slowing you down.

13Questions

Before you buy

Q1 Isn't this just an AI scanner with a human label on it?
No. An AI scanner flags the well-known misconfigurations and stops there — it doesn't understand your architecture, how your integrations fit together, your business logic, or the edge cases that actually break things. A senior engineer actually reads your code — the security- and production-critical parts — and catches the bug where your /admin route has no auth check, or where one tenant can read another's data. And when it's your business on the line, would you trust the same kind of AI that wrote the bug to also clear it?
Q2 What do you need from me to start?
Read-only access to your repository and a two-minute form describing what your app does and what you're worried about. We never ask for write access — we can't change, push, or delete anything.
Q3 Which languages and stacks do you review?
The tools founders actually build with — Next.js / React, Node, Python, and the usual backends (Supabase, Postgres, Firebase, Stripe). If you're not sure yours fits, ask before you buy and we'll tell you honestly.
Q4 Can I actually talk to the engineer who reviewed my code?
Yes — directly. After the report you take your follow-up questions straight to Shashank, the person who read your code. No ticket system, no chatbot, no account manager in between.
Q5 How fast do I get the report?
A complete, prioritized report within 48 hours of getting access — critical risks first, in plain English.
Q6 What if you don't find anything serious?
Then you launch with confidence — and you still get the full report and the call. We'd rather tell you you're in good shape than invent problems to look busy.
Q7 Can you fix the issues you find?
Yes, optionally. After the audit we quote the fixes clearly — no obligation. The $49 buys the review and the truth; whether we fix it is entirely your call.

Still have a question? Email [email protected] — ask before you buy, and we'll tell you honestly.

14Pays for itself

$49 that usually pays for itself — every month.

An audit doesn't just protect you. Vibe-coded apps quietly overspend, and a senior read finds the waste — so the $49 often comes back in the first month, then keeps saving.

Lower AI / token bills

Uncached and duplicate LLM calls, oversized context, retries, and endpoints with no rate limit — you pay for every wasted token. A review finds where they leak.

Cheaper cloud & hosting

N+1 queries, missing indexes and no caching make you over-provision and overpay. Fixing them drops your bill and your latency.

No surprise overnight bill

Rate limiting alone can stop a single abused endpoint from running up a four-figure charge — that's the $49 paid back a hundred times.

Do the math
If a senior review trims that by…
$64recovered / month
The $49 audit pays for itself in ~23 days — then it keeps saving.

Illustrative — actual waste depends on your code. Some apps have little; many vibe-coded ones have a lot. What's fixed: the audit is $49 once; any savings recur every month.
