Netlify Functions
Serverless functions built into every Netlify account. No setup, servers, or ops required.
Power your site without managing servers
Meet the modern backend. Infinitely scalable. Genuinely simple.
Serverless made painless
Run Lambda functions without touching AWS.
Setting up AWS Lambda functions on your own can be fairly complex. Tutorials average 20 steps! With Netlify, simply write your Lambda functions with JavaScript or Go and drop them into your functions folder. Everything else is automatic.
Functions that work as APIs
Your functions become endpoints, automatically.
Netlify deploys the functions you write as full API endpoints and will even run them automatically in response to events, like a form submission or a user login. Functions receive request context or event data, and return data back to your frontend.
Run functions in the background
Use Background Functions to get work done behind-the-scenes.
Most functions return a response immediately, but what if your task needs more time to process? Background Functions allow you to extend your execution time for up to 15 minutes without impacting your user’s experience.
Full-stack has never been easier
Netlify’s serverless functions can respond to events, sanitize user input, or know who’s logged in.
Automated triggers
Automatically trigger any function to run when a new deploy succeeds, a user authenticates, or a new form submission arrives.
Third-party APIs
Set up functions to check and sanitize user data before sending on to third-party APIs. Or use functions to process API responses and combine API services in new and exciting ways.
User authentication
Instead of managing sessions on a server, use JavaScript Web Tokens to handle identity right in the browser, passing session tokens directly to your serverless functions.
Less setup, more productivity
Functions as a Service (FaaS) providers like AWS handle some of the infrastructure hassle; Netlify takes the final step to bring functions directly to your workflow.

Decoupled but not divided
Frontend code & backend code in one powerful workflow.
Develop modularly. Deploy collectively
Atomically deploy your sites and apps, pushing frontend code and backend functions together, as a unit, without even requiring a maintenance window.
Stage, preview, and rollback
Netlify Functions share all of Netlify’s beloved workflow features. Preview every commit with Deploy Preview links. Rollback when needed by simply clicking a prior deployment.
Run A/B testing and phased rollouts Beta
Deploy and test multiple branches, and even control which users see which version. Plan full experiments and rolling upgrades that include both front and backend code changes. A/B test not just a button color, but an entire user workflow.
