# Building YepCodes: a coupon site that shows its record instead of a promise

Most coupon sites list codes nobody has checked in months, and mix every country together. We built YepCodes at Victor Studios around a simple rule: show the record, not a promise.

YepCodes is a coupon code website, with a Chrome extension coming soon, built on one shared database of codes. It is free, with no account or sign-up.

## The record on every code

- Each code shows when it last worked, if anyone has tried it.
- A code with no tries is marked **unverified**, rather than presented as working.
- Dead codes are removed.
- Codes are sorted for the shopper's country.

We chose to say "unverified" out loud because a coupon list that looks full is less useful than one that is honest about what nobody has checked yet.

## Who adds codes

Codes are added only by the YepCodes team, never by strangers or bots. That keeps the database small enough to stay accurate.

To make that practical, YepCodes runs an MCP server so AI agents can add stores, codes and deals in bulk. Every addition goes through a review queue with an audit log, so people keep the final say over what is published.

## Ranking without commission

YepCodes may earn a commission from stores, but only after a shopper clicks. Ranking uses evidence only and never sees commission. YepCodes also never replaces another site's or creator's affiliate link, and says so on every page.

## The extension, coming soon

The Chrome extension is in Chrome Web Store review. At checkout it adds a "Try all codes" button: it fills each code, reads the total and keeps the best one. It reads only the coupon field and the order total, only on supported stores, and only after you click.

## How it is built

The website is a Next.js app with React and TypeScript, styled with Tailwind CSS. The website and the extension share the same database of codes, and the MCP server feeds that database through the review queue.
