WebSocket
WebSocket is a TCP-based network communication protocol that provides a full-duplex, persistent connection channel between a client and a server. Unlike the traditional HTTP request-response model, once a WebSocket connection is established, both parties can push data at any time without repeated handshakes, significantly reducing communication latency and overhead. It is widely used in scenarios requiring low-latency bidirectional communication, such as real-time chat, online gaming, and live financial data feeds.
Core Facts
SSE or WebSocket protocols can push the model's token-by-token generated content to the front end in real time, enabling streaming responses from the Agent
WebSocket is a protocol for full-duplex communication over a single TCP connection, allowing the server to proactively push data to the client.
The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011.
Timeline (last 90 days)
The end-to-end latency of cloud browsers will be higher than running locally, because remotely driving a browser via WebSocket introduces extra network round trips.
Gologin Cloud Browser supports the two mainstream browser automation frameworks Playwright and Puppeteer via WebSocket.
The local Node server acts as the WebSocket server, and the WhatsApp script and the Claude.ai script act as clients that each establish a persistent connection to it.
The WhatsApp script only listens to whitelisted chats and ignores groups and historical messages; when a new message arrives, it sends it to the local server via WebSocket.
The engineering implementation of a 'two-way channel' usually takes two forms: in-process integration (LLM call logic written into game scripts, reading and writing world state through the engine's scripting API) and out-of-process communication (the game side opens a local service or message channel such as HTTP or WebSocket, and the agent runs as a separate process requesting state and issuing commands).
The Battledrones project previously or concurrently had an audio-channel-based online multiplayer approach, and v14 emphasizes using the non-audio WebSocket mode.
In multiplayer games, transmitting game state data over audio channels such as WebRTC is inferior to a dedicated WebSocket channel in bandwidth, latency, and data reliability.
Streaming recognition typically maintains a long connection via WebSocket and is suitable for interactive scenarios such as voice input methods and real-time subtitles; asynchronous recognition returns results via polling or webhooks and is better suited to offline scenarios such as recorded notes and meeting minutes.
In long tasks, simple polling is inefficient, and SSE or WebSocket are more common choices for streaming progress updates, but backpressure and reconnection must be handled to avoid duplicate or out-of-order events.
Pokémon Showdown supports programmatic battles via a WebSocket interface and provides an official `pokemon-showdown` npm package as well as client libraries for languages such as Python.
