WebSockets and AI
AI applications are driving a major shift from SSE to WebSockets. Bidirectional communication, connection resilience, and the emerging Durable Sessions category are changing how we build AI user experiences. Read the full guide.
WebSocket.org
The independent reference for everything WebSocket. Protocol deep dives, production patterns, and honest comparisons — built by practitioners, not vendors.
Understand the Protocol
Section titled “Understand the Protocol” The Road to WebSockets How we got from polling to persistent connections, and why it matters.
WebSocket Protocol Frames, handshakes, opcodes, and the wire format — the full picture.
WebSocket API The browser API: events, methods, readyState, and binary data.
Close Codes What 1006 actually means, and every other close code explained.
Build Something
Section titled “Build Something” Build Your First App A hands-on walkthrough from connection to production.
WebSockets at Scale Connection management, load balancing, and handling millions of clients.
Security Hardening CSWSH, authentication, rate limiting, and the attacks people forget about.
Testing with Autobahn Verify your implementation against the protocol spec.
Compare Protocols
Section titled “Compare Protocols”Not everything needs a WebSocket. These comparisons help you pick the right tool.
WebSockets vs SSE The most common choice in AI streaming — and where SSE falls short.
WebSockets vs HTTP When a persistent connection beats request-response.
WebSockets vs WebTransport The next-gen contender built on HTTP/3 and QUIC.
All Comparisons MQTT, gRPC, WebRTC, long polling, and the decision matrix.
What’s New
Section titled “What’s New”By Language
Section titled “By Language”Production-ready patterns for your stack.
Infrastructure
Section titled “Infrastructure”Deploying WebSockets in production means configuring proxies, load balancers, and timeouts correctly. These guides cover the specifics.
Nginx Proxy pass, upstream keepalive, and timeout tuning.
AWS ALB Target groups, sticky sessions, and idle timeout gotchas.
Cloudflare WebSocket support through Cloudflare's proxy and Workers.
Kubernetes Ingress controllers, session affinity, and scaling pods.
