# Overview
Edge Flags is a low latency feature flagging solution running at the edge and
storing data in a global Redis database. It is designed to be used with
[Next.js](https://nextjs.org) and [Vercel](https://vercel.com) but we will soon
roll out support for other popular frameworks and platforms. Let us know what
you are looking for!
You can find the Github Repository [here](https://github.com/upstash/edge-flags).
## Features
* **Global Low latency:** Flags are stored in a global Redis database and are
evaluated at the edge.
* **Environments:** Flags have different environments to support your deployment
process: `production`, `preview`, `development`
* **Flexible:** Flags support geo targeting, percentage based rollouts and
custom attributes
* **Manage:** Flags can be created and managed using the SDK or our
[console](https://console.upstash.com/edge-flags).
* **Free:** Edge Flags is free to use. You only pay for the Redis database.
* **Cache:** Flags can be cached for a short period of time to reduce the
required requests to redis, making it cheaper to use.
