Overview

Netlify Functions provide a simple way to add serverless backend logic to your Netlify-hosted sites, with generous free tier limits and easy deployment.

Good fit

Use when you need to add backend logic or APIs to static sites without managing servers.

  • jamstack sites
  • static site APIs
  • simple backend tasks

Not a fit

Avoid if you need long-running processes, high memory, or custom runtime environments.

  • heavy computation
  • custom runtimes
  • stateful services
