A few years ago, we started Twilio to let any developer build apps that communicate with the phone network. Today, we see awesome communication experiences beginning to permeate the web, and mobile apps have become a full-feldged peer of the web.
We built Twilio Client to give every developer, whether web or mobile, at big companies and small, the ability to build world-class communications awesomeness into their apps. We hope you have fun reinventing the way your users communicate. We can't wait to see what you build.
If robustness and reliability are as important to your application as they are to us, you'll be writing tests to ensure your customers always have a great experience. With Twilio's Test Credentials you can test those pesky telecom edge-cases, from buying a phone-number in Portugal to placing a call to Peru. All without spending a penny.
