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.

ParityEdge is an edge-powered pricing localization platform that automatically offers fair, country-specific discounts to visitors worldwide, helping you convert international traffic into recurring revenue with zero checkout friction.

What does ParityEdge do?

If you sell a software subscription for $49 USD/month, that price is reasonable in New York, London, or Tokyo. But in India, Brazil, or Nigeria, $49 can equal 15% or more of an engineer's monthly take-home pay. Visitors leave without buying.

ParityEdge solves this seamlessly: it detects your visitor's country in under 10 milliseconds, shows a tasteful discount banner (e.g. 50% off in India), and automatically fills the coupon into Stripe or Lemon Squeezy checkout. You make global sales you would have otherwise lost forever.

Why Purchasing Power Parity (PPP) Matters

When software and SaaS businesses sell at a uniform price (e.g., $49/month), pricing becomes unaffordable in emerging markets where the average software engineer or creator earns a fraction of Western salaries.

Without ParityEdge (Flat Global Pricing)

A $100 developer tool represents 0.2% of monthly disposable income in the US, but over 15% in India or Nigeria. Visitors churn immediately, resulting in 99%+ checkout abandonment in emerging markets.

With ParityEdge (Automatic Regional Pricing)

Visitors automatically receive localized discounts (e.g., 50% in Tier 3 markets) with customized checkout promo codes prefilled on Stripe, significantly boosting international checkout conversions.

The Sub-10ms Request Lifecycle

Unlike legacy IP lookup APIs that introduce 200–500ms network delays and layout shifts (CLS), ParityEdge runs at the edge within our global Anycast network:

Edge Geolocation & VPN Verification

The edge engine reads incoming connection metadata (country code and network). If traffic originates from a datacenter hosting proxy (AWS, GCP, DigitalOcean), standard full pricing is safely maintained without annoying alerts.

Sub-10ms Memory Lookup

Project discount rules and country overrides are fetched directly from distributed edge cache memory without issuing slow database queries to an origin server.

Isolated Banner & Instant Checkout Auto-Fill

A localized banner mounts inside an isolated Shadow DOM container (so your website CSS never breaks), and Stripe checkout links (`buy.stripe.com`) receive the prefilled coupon code automatically.
