Real-Time Applications
Pricing

Use WebSockets when you need two-way, low-latency communication — chat, collaborative editing, multiplayer. Use Server-Sent Events when data only flows one way, server to client, like a live price ticker or notification feed; SSE is simpler, runs over plain HTTP, and reconnects automatically. Many apps use SSE where they can and reserve WebSockets for genuinely bidirectional features. We pick per feature, not one for everything.
