WebSockets

Pick WebSocket when you need low-latency, high-frequency, bidirectional traffic through a browser: multiplayer state sync, trading tickers, collaborative editors, where SSE's one-way stream or MQTT's broker overhead don't fit

Pros

• Skip it for simple server-push (stock ticker, notification feed): SSE rides plain HTTP, auto-reconnects, and survives corporate proxies that WebSocket's upgrade handshake can get blocked by, at a fraction of the code
• Related to: http-2, grpc

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Messaging APIs is a platform while WebSockets is a protocol. We picked Messaging APIs based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Messaging APIs wins

Based on overall popularity. Messaging APIs is more widely used, but WebSockets excels in its own space.
