Daily Realtime Video API

Daily is a realtime voice, video, and artificial intelligence communication platform founded in 2016, providing WebRTC infrastructure and APIs for building video calling, voice chat, live streaming, and conversational artificial intelligence applications. The platform operates a global mesh network with over seventy-five points of presence worldwide, achieving a median first-hop latency of thirteen milliseconds, with automatic regional routing that connects participants to the nearest media server for optimal call quality. Daily offers a JavaScript SDK for embedding video calls into web applications with a prebuilt user interface component for drop-in video conferencing, and a lower-level SDK for custom layouts and branded experiences. The platform supports simulcast and scalable video coding for adaptive bitrate streaming, virtual backgrounds through TensorFlow body segmentation, screen sharing with system audio capture, recording with cloud storage and download, live streaming to RTMP destinations including YouTube and Twitch, and real-time transcription through speech-to-text integration. The conversational AI capabilities include the open-source Pipecat framework for building voice-based AI agents that can listen, reason, and respond in real time during video calls, with support for speech interruption, turn-taking, and multi-modal responses. Daily is SOC-2 Type 2 certified, GDPR compliant, and HIPAA compliant, adopted by companies including NVIDIA, Epic Games, Cresta, Mercor, Tavus, HeyGen, Vapi, and Cal.com for their real-time communication infrastructure.
