Serverless use cases

Unlock endless possibilities when you go serverless. Discover our most popular applications.

Deploy an SMS app in five minutes

Launch and test an SMS auto-response application with Twilio Functions. With just a few lines of code, you’ll see your phone light up with “Hello World” from your Twilio phone number.

Create SMS auto-response

“You don’t have to comment out lines of code to explain what a function is doing. The Twilio code is really clear and easily configured.”

Nate Grief Product Owner, VictorOps

Build integrated IVRs for self-service

Set up a basic IVR (interactive voice response) app for your business using Twilio Studio’s drag-and-drop builder. With IVR, you can create a phone menu that’s easy to navigate by voice or keypress, and route users’ calls to the correct department in a snap.

Create an IVR

Chime used Studio to build a highly personalized IVR solution for all levels of inbound support that they could quickly iterate and improve.
