Faye vs TIBCO FTL

Faye is a publish-subscribe messaging system that uses the Bayeux protocol. It provides message servers for Node.js and Ruby, plus clients for servers and major web browsers. Browser clients rely on a Faye server to relay messages; they can retry after a lost connection and redeliver dropped messages. Transport adapters cover WebSocket, HTTP long-polling, Cross Origin Resource Sharing, and JSON-P callback-polling. Server and client extensions can intercept or modify messages, including to add subscription authentication. The monitoring API reports handshakes, subscriptions, unsubscriptions, publishes, and disconnections. Faye runs on Linux, macOS, and Windows, and can be self-hosted. Its default in-process engine cannot span multiple front-end web servers, but Redis and Couchbase engines are documented for distributed deployments. Faye is free and open source under the Apache 2.0 license; the listed plan is free. Install the Node.js server through npm or the Ruby server through RubyGems.

TIBCO FTL is an application-to-application messaging system designed for low latency and high performance. Applications can exchange messages through brokers or directly with one another using peer-to-peer messaging. Messages contain named fields with typed values, and subscribers can use content matchers to select them. Persistence services retain messages for durable subscribers and replicate message and acknowledgement data across services for fault tolerance. API references are listed for C,.NET, Java, and Go; TIBCO also describes messaging for REST, web, and mobile-based devices. Security documentation covers authentication, authorization, TLS, secure transports, and server data directories. FTL channels enable publish-subscribe messaging among eFTL applications and between eFTL and FTL applications. Listed platforms include API, Linux, macOS, self-hosted, web, and Windows. The Community Edition is listed at free. Enterprise Edition pricing is on request, and a non-expired license is required to start it. TIBCO lists online support cases and live chat available around the clock for other assistance.
