Introduction

Edge Realtime SDK is a lightweight realtime streaming library with a single transport (WebSocket) and a small server-side authorization layer.

Why?

• Long-polling fallbacks are wasteful at scale.
• Server-Sent Events lack bidirectional framing.
• WebRTC is overkill for application-level realtime data.

The Realtime SDK provides a thin, well-defined WebSocket protocol with subscription, presence, and event push.
