The post provides a decision framework, noting SSE is ideal for live dashboards and AI streaming, while WebSockets should be reserved for bidirectional needs like chat and multiplayer games. The developer warns that choosing unnecessarily complex technology adds infrastructure costs and maintenance burdens.", "body_md": "When developers hear \"real-time communication,\" the first thing that comes to mind is usually WebSockets.\n\nBut here's the thing:\n\n**WebSockets are not always the best solution.**\n\nChoosing the wrong real-time technology can add unnecessary complexity, infrastructure costs, and maintenance headaches.\n\nLet's look at some alternatives and when you should use them.\n\nSSE allows the server to push updates to the client over a regular HTTP connection.\n\nPerfect for:\n\n✅ Live dashboards\n\n✅ Notifications\n\n✅ AI response streaming (like ChatGPT)\n\n✅ Monitoring systems\n\nExample:\n\n``` js\nconst eventSource = new EventSource(\"/events\");\n\neventSource.onmessage = (event) => {\n  console.log(event.data);\n};\n```\n\nWhy I like it:\n\nBefore WebSockets became popular, long polling was the go-to approach.\n\nHow it works:\n\nUseful for:\n\n✅ Legacy systems\n\n✅ Simple notification services\n\nNot ideal for high-frequency updates.\n\nWebRTC enables direct peer-to-peer communication.\n\nBest for:\n\n✅ Video calls\n\n✅ Voice calls\n\n✅ Screen sharing\n\n✅ P2P data transfer\n\nThis is what powers many modern meeting applications.\n\nWith HTTP/2 and modern browsers, streaming data continuously is easier than ever.\n\nUseful for:\n\n✅ AI-generated content streaming\n\n✅ Real-time logs\n\n✅ Analytics dashboards\n\nUse WebSockets when you need:\n\n✅ Bidirectional communication\n\n✅ Chat applications\n\n✅ Multiplayer games\n\n✅ Collaborative editing tools\n\n✅ Trading platforms\n\n| Use Case | Recommended Technology |\n|---|---|\n| AI Streaming | SSE |\n| Notifications | SSE |\n| Live Dashboard | SSE |\n| Chat App | WebSocket |\n| Multiplayer Game | WebSocket |\n| Video Call | WebRTC |\n| Legacy Systems | Long Polling |\n\nOne of the biggest engineering mistakes is choosing a more complex solution when a simpler one would work perfectly.\n\nNot every real-time application needs WebSockets.\n\nSometimes a simple SSE connection is all you need.\n\nWhat real-time technology are you using in production today?", "url": "https://wpnews.pro/news/stop-using-websockets-for-everything", "canonical_source": "https://dev.to/koolkamalkishor/stop-using-websockets-for-everything-3l26", "published_at": "2026-05-29 13:06:34+00:00", "updated_at": "2026-05-29 13:11:20.130001+00:00", "lang": "en", "topics": ["ai-tools", "ai-infrastructure", "ai-products"], "entities": ["WebSockets", "SSE", "WebRTC", "HTTP/2", "ChatGPT", "EventSource"], "alternates": {"html": "https://wpnews.pro/news/stop-using-websockets-for-everything", "markdown": "https://wpnews.pro/news/stop-using-websockets-for-everything.md", "text": "https://wpnews.pro/news/stop-using-websockets-for-everything.txt", "jsonld": "https://wpnews.pro/news/stop-using-websockets-for-everything.jsonld"}}
