Netlify Functions

Netlify Functions are zero-config, serverless functions that deploy instantly as API endpoints alongside your frontend code.

Netlify Functions provide a streamlined serverless platform: write your code in JavaScript, TypeScript, or Go, and drop the files into your project's `netlify/functions` folder. The platform automatically handles deployment, version control, and scaling, leveraging AWS Lambda under the hood. This tight integration means your backend logic (like processing form submissions or hitting a third-party API securely) is deployed and previewed with your frontend code, simplifying the entire Git-based workflow. Every function gets a dedicated, auto-generated endpoint, such as `https://<DOMAIN>/.netlify/functions/hello`, which you can test locally using the Netlify CLI.
