The client opens a connection with the browser's `EventSource` API (or an equivalent library) and the server keeps it open, emitting text events as `data:` lines whenever something new happens. Unlike WebSockets, SSE is unidirectional — server to client only — which makes it simpler to run: it rides on ordinary HTTP, reconnects automatically, and passes through most proxies and load balancers without special handling. For AI SaaS builders this is the workhorse behind token-by-token streaming: most LLM APIs stream their responses as SSE so users see text appear as it's generated instead of waiting for the whole completion. It's also a clean fit for live dashboards, notifications, and progress bars. The catch: it only carries text and browsers cap the number of open connections, so it's not for high-frequency bidirectional traffic.","Server-Sent Events push a one-way stream of updates over a single long-lived HTTP connection — simpler than WebSockets and exactly what LLM token streaming uses.",null,[11,14,17,20],{"slug":12,"name":13},"grpc","gRPC",{"slug":15,"name":16},"publish-subscribe","Publish\u002FSubscribe (Pub\u002FSub)",{"slug":18,"name":19},"streaming-data-processing","Streaming Data Processing",{"slug":21,"name":22},"webhook","Webhook",[24,28,31,34,37,40,42,45,48,51,54,57],{"slug":25,"category":5,"name":26,"updated_at":27},"backend-for-frontend","Backend for Frontend (BFF)","2026-08-24T02:46:38+00:00",{"slug":29,"category":5,"name":30,"updated_at":27},"concurrency-limit","Concurrency Limit",{"slug":32,"category":5,"name":33,"updated_at":27},"event-ordering","Event Ordering",{"slug":35,"category":5,"name":36,"updated_at":27},"field-mapping","Field Mapping",{"slug":38,"category":5,"name":39,"updated_at":27},"function-schema","Function Schema",{"slug":12,"category":5,"name":13,"updated_at":41},"2026-08-24T02:46:37+00:00",{"slug":43,"category":5,"name":44,"updated_at":27},"integration-marketplace","Integration Marketplace",{"slug":46,"category":5,"name":47,"updated_at":27},"ip-allowlist","IP Allowlist",{"slug":49,"category":5,"name":50,"updated_at":27},"json-web-token","JSON Web Token (JWT)",{"slug":52,"category":5,"name":53,"updated_at":27},"mcp-server","MCP Server",{"slug":55,"category":5,"name":56,"updated_at":27},"mutual-tls","Mutual TLS (mTLS)",{"slug":58,"category":5,"name":59,"updated_at":27},"oauth-scopes","OAuth Scopes"]
