## What it is
iComet is a high-concurrency comet/server-push messaging server written in C++ with libevent, designed to handle a million concurrent connections (C1000K). It ships with a JavaScript client library and supports HTTP long-polling subscriptions for web, mobile, and desktop apps.

## Use cases
- add server-push notifications to a web app
- build a real-time web chat
- push messages to mobile applications
- implement pub/sub channels over HTTP long-polling
- handle millions of concurrent push connections
- integrate server push behind nginx on port 80

## When to choose
- you need a lightweight, self-hosted push server with very high connection counts
- your clients are browsers or mobile apps that can't hold persistent websockets
- you want a simple HTTP subscribe/push API with a ready-made JS client

## When to avoid
- you need modern WebSocket or SSE support with active maintenance
- you want a managed cloud messaging service
- your stack is Node.js or Go and a maintained library there fits better

## Facets
- artifact type: service
- maturity: maintenance
- function: http-server, websocket, message-queue, middleware
- domain: web-development, backend
- platform: cpp, self-hosted
