What is ParityEdge and what does it do?

ParityEdge is a sub-10ms edge Purchasing Power Parity (PPP) localization platform and developer SDK. It converts global SaaS pricing into regional discounts across 190+ countries, injects coupons into Stripe and Lemon Squeezy checkouts, and renders isolated Shadow DOM banners with near-zero layout shift (<0.01 CLS).

How do I install the parityedge npm package?

You can install the official parityedge package via npm by running `npm install parityedge` (or `pnpm add parityedge`, `yarn add parityedge`). It has zero third-party runtime dependencies and is under 3 kB gzipped.

How does ParityEdge prevent VPN abuse on discounted pricing?

ParityEdge inspects incoming Autonomous System Numbers (ASNs) at the edge against a comprehensive threat database of 500+ commercial datacenter and proxy providers (such as AWS, Google Cloud, DigitalOcean, Hetzner). Datacenter and VPN visitors are automatically served standard base pricing to stop geographic arbitrage.

How do I use ParityEdge with React and Next.js 15?

After installing `parityedge`, import the React hook and banner component: `import { useParityEdge, ParityBanner } from "parityedge/react";`. It provides zero-flicker SSR hydration and automatic price mutation.
