# What is ApiRTC?

ApiRTC is a platform that enables developers to easily add real-time video chat functionality to their applications using APIs and client-side SDKs. 

It provides the necessary infrastructure for signaling, media processing, and media delivery to enable real-time communications based on the [WebRTC standard protocol](https://webrtc.org/). ApiRTC also offers global STUN/TURN relays, media services for one-to-one calls or large group conferences and recording, and the ability to customize, troubleshoot, and optimize video applications using a range of tools. 

Media exchange can occur either directly peer-to-peer or through ApiRTC's servers, depending on the chosen Video Room type. Signaling is managed through ApiRTC's global infrastructure to facilitate the setup, control, and termination of RTC sessions.

## Where to start with ApiRTC?

* Read the [Video Communication LifeCycle](/apirtc-developer-portal/apirtc-js-library/video-communication-lifecycle.md) guide
* Play with the [Demo App & Resources](/apirtc-developer-portal/apirtc-js-library/demo-app-and-resources.md)
