# Functions

Last updated Sep 1, 2026|Copy as Markdown| [View as Markdown](https://0285ca83.previews.developers.cloudflare.com/pages/functions/index.md)| [Agent setup](https://0285ca83.previews.developers.cloudflare.com/agent-setup/)

Pages Functions allows you to build full-stack applications by executing code on the Cloudflare network with [Cloudflare Workers](https://0285ca83.previews.developers.cloudflare.com/workers/). With Functions, you can introduce application aspects such as authenticating, handling form submissions, or working with middleware. [Workers runtime features](https://0285ca83.previews.developers.cloudflare.com/workers/runtime-apis/) are configurable on Pages Functions, including [compatibility with a subset of Node.js APIs](https://0285ca83.previews.developers.cloudflare.com/workers/runtime-apis/nodejs) and the ability to set a [compatibility date or compatibility flag](https://0285ca83.previews.developers.cloudflare.com/workers/configuration/compatibility-dates/). Use Functions to deploy server-side code to enable dynamic functionality without running a dedicated server.
