WebSocket Protocol
Bidirectional communication protocol enabling real-time agent-to-agent messaging and persistent connections for agent coordination.
Viable option — review the tradeoffs
You need bidirectional, low-latency communication for real-time agent coordination like live updates or multiplayer interactions without polling overhead.
Sub-100ms latency at scale with proper engineering; quirks include manual reconnection logic, no built-in auth/retry, and proxy/firewall compatibility issues.
You want to build collaborative agents or live feeds where multiple agents must sync state in real-time without constant HTTP requests.
Reliable for millions of connections with delta encoding and non-blocking I/O; expect higher memory use from persistent connections.
No Built-in Reliability Features
Lacks automatic reconnection, heartbeats, or message queuing; builders must implement ping/pong, reconnections, and offline buffering manually.
Proxy and Firewall Gotchas
Some proxies drop idle connections or block ws:// upgrades; use wss:// (TLS), configure keep-alives, and test with sticky sessions to avoid silent failures.
WebSocket wins for true real-time; long-polling is fallback for legacy networks.
Need full-duplex, low-latency bidirectional comms at scale.
Environments blocking WebSockets or minimal real-time needs.
Trust Breakdown
What It Actually Does
Enables agents to send and receive messages instantly over a persistent connection, letting them coordinate work in real time without constant reconnections.
