The record

Purpose: Faye is a publish-subscribe messaging system based on the Bayeux protocol.
Server and clients: It provides message servers for Node.js and Ruby and clients for servers and major web browsers.
Browser requirement: Browser clients require a Faye server to handle message delivery between clients.
Messaging transports: The adapters support WebSocket, HTTP long-polling, Cross Origin Resource Sharing, and JSON-P callback-polling.
Client recovery: The browser client periodically retries after a lost connection and can redeliver dropped messages.
Scaling: The default in-process engine cannot run one Faye service across multiple front-end web servers; separate Redis and Couchbase engines are documented for distributed deployments.
Integrations: The download instructions provide installation through npm for Node.js and RubyGems for Ruby.
Extensions: Server and client extensions can intercept and modify incoming or outgoing messages, including to implement subscription authentication.
Security: Faye allows cross-domain access and unrestricted publishing and subscribing by default, so the documentation advises adding application-appropriate restrictions.
Transport security: The security guide advises using HTTPS to protect messages and the HTTP transport from eavesdroppers.
Monitoring: The monitoring API can report client handshakes, subscriptions, unsubscriptions, publishes, and disconnections.
Notable browser limit: The documentation advises creating one client per target server because browsers impose per-host connection limits.
License and release: The site lists version 1.4.2, released 14 September 2026, under the Apache 2.0 license.
Maker: The site credits James Coglan as Faye’s maker.
