We don't have
a developer
Former-CTO working experts with 10+ years each in Web, Backend, Android, and iOS review the code you built with vibe coding in detail.
The review report also covers what you'll need for operations — env variables, cloud deployment, and more.!
Outsourcing quotes vary so wildly,
how do I even choose?
A transparent pricing system means fair prices for extra work. You can outsource just a single feature, like payments or social login.
We also handle the hard parts for you — building the admin dashboard and PG payment approval.!
Keep vibe coding,
we'll keep checking it
Focus on validating your market. We'll keep verifying it's built right, every time you deploy.
We'll keep watching at a reasonable cost, so your launches, edits, and deploys stay just as fast.!
Am I doing
vibe coding right?
Going it alone without dev knowledge has its limits. Prompt and rule setup changes your code quality — we'll help you get it right.
For our clients, we provide per-AI guides built on our review know-how.!

Frequently asked questions
The questions we get most about scope, turnaround, pricing, and how your code is handled.
We review your uploaded code against 45 security, reliability, and cost checks. The focus is on critical issues such as payment amount tampering, exposed secrets, authorization bypass (IDOR), RLS configuration, and unauthenticated calls to paid APIs. The review is limited to code, UI, and process; it does not include legal advice or similar services.
It varies with codebase size and the number of checks, but typically takes 2 to 7 days. We start as soon as your payment is confirmed and keep you updated on the service screen and by email.
Source code is accessed read-only. After the review, unless you continue with a maintenance contract or similar engagement, it is discarded after a set period.
SSR frameworks such as Next.js and Nuxt, servers built with FastAPI, Express, or NestJS, Supabase and Firebase, and mobile apps built with Expo, React Native, or Flutter. Whether you used Claude, Cursor, Lovable, Bolt, or v0, just zip the project and upload it.
The report explains the cause and fix for each issue, so you can apply the fixes yourself. For harder pieces such as payment integration, social login, or an admin page, you can outsource individual features to us, and we also help prepare for payment gateway certification. Outsourcing is quoted separately.
After reviewing the quote, you make a bank transfer to the account shown; once the Cestdi team confirms the deposit, the review begins. Tax invoices are available on request. See the Terms of Service for details.
You receive a PDF report listing the findings in order of severity. Each finding includes its impact, cause, and fix, along with operational notes such as environment variable setup and cloud deployment. It is written so that non-engineers can read it.
