CodeXhange
CodeXhange is a gamified promo code search engine — the best place to find working coupon codes, discount codes, and deals that actually work. Built with Next.js, TypeScript, and MongoDB, it uses ISR brand pages, dynamic meta tags and hreflang for SEO, Cloudflare Turnstile bot protection, and NextAuth for contributors. A self-cleaning reputation system keeps every code verified and current.
The Problem
Most coupon sites are graveyards of expired codes. Users burn time testing dead discounts, and brands lose conversions because there is no trustworthy middle layer between shoppers and real, working codes.
The Solution
CodeXhange turns verification into a game. A self-cleaning reputation system scores every code by real usage, expired codes decay automatically, and contributors are rewarded for keeping codes fresh — so search results surface codes that actually work.
