ParticipantsPurpleCallio vs building WebRTC yourself
When building directly with WebRTC, developers still need to design signaling, session management, authentication boundaries, participant state, media permissions, connection lifecycle, WebRTC state, and TURN connectivity. PurpleCallio provides the integration surfaces around those concerns while your application retains control of its product flow and interface.
Security
Project API key: server only
Never expose the project API key in frontend or browser code.
Browser: session information only
Your backend authorizes application users and returns the participant-specific information needed to join.
Pricing
PurpleCallio uses usage-based participant-minute pricing. Audio, video, and screen sharing are separate usage categories.
