Twilio
Twilio is a cloud communications platform that provides APIs for developers to build and integrate voice, video, messaging, and email capabilities into their applications. It abstracts the complexity of telecom infrastructure, allowing developers to add communication features without managing underlying hardware or carrier networks. The platform supports global reach with scalable, pay-as-you-go services.
Developers should learn Twilio when building applications that require real-time communication features, such as SMS notifications, voice calls, video conferencing, or two-factor authentication. It is particularly useful for customer engagement, appointment reminders, and emergency alerts, as it simplifies compliance with telecom regulations and offers reliable delivery across carriers worldwide.
