What it is

Daily.co provides WebRTC infrastructure (SFU, recording, transcription) underneath many voice-AI builders, including its own Pipecat framework and Daily Bots service. Buyers use Daily.co directly when they need browser-native realtime audio for in-app voice agents and want fine control over the transport layer.

Best for: Browser-first voice and video AI agents that need reliable WebRTC SFU.
Watch out for: WebRTC focus — PSTN/SIP requires partner integration.
