+title: How to upgrade to Next.js Canary
+nav_title: Canary
+description: Upgrade your Next.js Application to canary and try out new features.
+---
+
+The Next.js canary channel is updated daily with the latest experimental features and bug fixes. It's a great way to try out new features and [give feedback](https://github.com/vercel/next.js/issues) before they are released in a stable version.
+
+To upgrade to canary, make sure you're on the latest version of Next.js and everything is working as expected. See the [upgrade guides](/docs/app/building-your-application/upgrading) for more information.
+
+Then, run the following command:
+
+```bash filename="Terminal"
+npm i next@canary
+# or
+yarn add next@canary
+# or
+pnpm i next@canary
+```
+
