Workers KV makes it possible to move applications which otherwise would have to live in a central origin onto our network.
With KV you can store your access tokens inside our network. This will allow you to make authentication decisions faster than a traditional request can even get to your origin, and will allow you to move all of your authentication logic to one place.
Store customer profiles in our network to make it possible to deliver customized pages with the performance of a static file on a CDN. Common use cases include A/B testing, 'logged in' state, translations, CMS-style content management, retargeting, and even showing product recommendations.
KV data can be used to configure your existing Workers, or to deliver configuration to the client-side portion of your websites. You can create feature flags, kill switches, even block malicious users, all with data stored in KV.
Workers KV isn't just for applications which need exceptional performance. It often simply makes more sense to run code all around the world close to every user than to deploy it to a single location. We have customers who use Workers KV to handle webhooks, to synchronize data between systems, to build chat bots, and to log data. Build your entire API as a Worker and serve your full website from a Worker using Workers KV.
