You could build geo-targeting yourself: write middleware, set up an IP database, handle caching edge cases, manage hreflang, detect bots. Or paste one script tag and get all of it working in 3 minutes. GeoSwap works with App Router, Pages Router, and Vercel Edge.
You absolutely can. Next.js middleware + a geo-IP database + some caching logic gives you full control. But you'll spend days on edge cases: handling bot detection correctly, generating hreflang tags, avoiding cloaking penalties, dealing with ISR cache invalidation. GeoSwap handles all of that out of the box, runs on its own edge infrastructure (so it doesn't consume your Vercel Edge Function quota), and gives you a dashboard instead of code to maintain.
GeoSwap runs at the edge independently of your rendering strategy. Server-rendered, statically generated, incrementally regenerated — geo-targeting works the same.
Add the script in layout.tsx or _document.tsx — same result either way. Works with React Server Components, client components, and everything in between.
GeoSwap runs on its own Cloudflare edge infrastructure. It doesn't consume Vercel Edge Function invocations or add to your Vercel bill.
The @geoswap/next package provides a native React component wrapper, next/script optimization, and full TypeScript types. Use it if you prefer npm over a script tag.

Skip the IP databases, bot detection edge cases, and hreflang headaches. GeoSwap gives you a dashboard instead of code to maintain. Free forever.
