Experiment at the edge
Vercel's Edge Network gives you access to powerful compute without added latency. Test locally, deploy globally, with zero configuration.
Better performance
Less code shipped to the browser means better performance on any network.
No configuration
Define your application's global infrastructure directly from your code.
Seamless staging
Get the full picture of how your code works in production.
EDGE FUNCTIONS
Dynamic at the speed of static
The benefits of serverless compute, with the speed of global replication. Personalize experiences for each user without the overhead of added infrastructure maintenance or latency.
Vercel is working with partners from across the industry to develop open standards for Edge Compute, and provide everyone with the tools to build for the future of web infrastructure.
Build your functions with JavaScript, TypeScript, or any language that compiles to WebAssembly (Wasm).
Deploy your functions globally or in a single region to minimize latency to your customers or to your data fetching at the edge.
âWe can show the control or experiment version of a page immediately instead of using third-party scripts. This results in better performance and removes the likelihood of flickering/layout shifts.â

EDGE MIDDLEWARE
Compute before the cache
When compute happens instantly, routing decisions can be made before the cache. Making A/B testing and feature flagging possible without added third-party scripts or client-side JavaScript.
Middleware is designed to run before serving requests from the edge cache, to enable instant rewrites and redirects.
When deployed to Vercel, Middleware is automatically configured as a special set of Edge Functions that are deployed globally with zero cold boots.

CUSTOMIZE
Fast, flexible personalization
The first impressions of a site are made in the first 50 milliseconds of viewing. With Edge Middleware, users will only see what you want them to see.
Safely pre-deploy multiple versions of your site and route users to the correct version at runtimeâwithout any delays.
PROTECT
Full routing & access control
Prevent unwanted traffic spikes and protect against attacks by using integrations with bot detection, like DataDome, that allow you to check who is visiting your site.
With simple authentication from a single route, you can check for cookies and perform rewrites at the edge, always ensuring youâre sending users to the correct version of the page.
âWeâre excited to leverage Vercel platform features like Edge Middleware that will allow us to continue delivering delightful experiences on the web with the same level of performance that our customers have come to expect of our products.â
