## What it is
Juggernaut is a deprecated Node.js realtime server-push service that lets web applications push data to browsers over WebSockets with fallbacks to Comet-style transports. It uses Redis for pub/sub scaling and ships an optional Ruby client gem.

## Use cases
- push realtime updates from server to browsers
- build a chat application with live messages
- add live notifications to a web app
- stream multiplayer game events to clients
- group collaboration with live data sync
- fallback realtime transport for old browsers without WebSocket

## When to choose
- maintaining a legacy Ruby/Node stack that already depends on Juggernaut
- studying historical realtime push implementations

## When to avoid
- starting any new project - it is deprecated and unmaintained since 2012
- you need modern WebSocket support - use Socket.IO, Action Cable, or native WebSockets
- you need long-term support or security updates

## Facets
- artifact type: service
- maturity: abandoned
- function: websocket, message-queue, http-server
- domain: web-development
- platform: -
- tags: server-push, comet, pubsub, deprecated, redis, ruby-client, real-time, messaging, nodejs, web-server
