Netlify Functions
Deploy server-side code that works as API endpoints, runs automatically in response to events, or handles more complex jobs.
Overview
Netlify Functions allow you to run on-demand, server-side code without having to run a dedicated server. You can use functions to build a complete API for your web app, handle user authentication, process form submissions, and more. They are version-controlled, deployed with your site, and scale automatically.
✨ Key Features
- Git-based deployment
- Automatic scaling
- Support for JavaScript, TypeScript, and Go
- Scheduled functions (cron jobs)
- Background functions for longer-running tasks
- Integrated with the Netlify platform
🎯 Key Differentiators
- Deeply integrated into the Netlify workflow for building and deploying Jamstack sites
- Simple, file-based routing for functions
- Support for background functions for longer tasks
Unique Value: The simplest way to add scalable backend functionality to your Jamstack sites, deployed with your frontend code.
🎯 Use Cases (5)
✅ Best For
- Backend for static sites
- Serverless APIs
- Event-triggered automation
💡 Check With Vendor
Verify these considerations match your specific requirements:
- CPU-intensive, long-running computations not suitable for background functions
- Applications requiring a persistent server connection
🏆 Alternatives
