# Setting up Vercel

> Integrate Kameleoon with Vercel Edge Functions to run server-side experiments at the edge, delivering personalized content with minimal latency for Next.js applications.

## Overview[​](#overview "Direct link to Overview")

By using [Vercel Edge Functions](https://vercel.com/features/edge-functions) with Kameleoon, personalized content can be efficiently delivered to website visitors. These edge functions deploy globally via the Vercel Edge Network, allowing server-side logic to reside closer to users for swift and efficient content delivery. For [NextJS](https://nextjs.org/) applications on Vercel, the Kameleoon integration facilitates experimentation directly at the edge. The Kameleoon Vercel Integration streamlines the initialization of Vercel projects by pushing Kameleoon configurations directly to Vercel's Edge Config.

Vercel enforces size limits on Edge Config values. Given these limits, Vercel Enterprise and Pro customers with moderately-sized environments stand to benefit most from this integration. For further details, consult Vercel's documentation on [Edge Config Limits and pricing](https://vercel.com/docs/storage/edge-config/edge-config-limits).
