SDK stands for Software Development Kit.

An SDK is a collection of tools, libraries, documentation, and code samples that developers use to build applications for a specific platform or technology.

WebRTC SDKs

In the WebRTC ecosystem, SDKs come in two main categories:

Client-side SDKs provide pre-built WebRTC functionality for applications:

  • Browser-based JavaScript SDKs that wrap the raw WebRTC APIs with easier-to-use abstractions
  • Native mobile SDKs (iOS/Android) that embed libWebRTC and provide platform-specific APIs
  • Desktop SDKs for Electron or native applications

Server-side SDKs help developers interact with WebRTC infrastructure:

  • Media server SDKs for building custom SFU or MCU functionality
  • Signaling server SDKs
  • CPaaS platform SDKs (Twilio, Vonage, etc.)

Most CPaaS vendors provide SDKs as their primary developer interface, abstracting away the complexity of raw WebRTC development while offering features like room management, recording, and analytics.
