## What it is
Jackal is a free, open-source, high-performance XMPP (Jabber) instant messaging server written in Go. It emphasizes stability, simple configuration, and low resource consumption, with clustering, caching, and Prometheus metrics support.

## Use cases
- self-host an XMPP chat server
- run a private instant messaging server for my team
- deploy a scalable federated messaging server
- set up an XMPP server for IoT device messaging
- host a Jabber server with clustering and Redis caching
- replace proprietary chat backends with an open-source XMPP server

## When to choose
- you need a lightweight, low-resource XMPP server
- you want clustering support with etcd for horizontal scaling
- you prefer simple YAML configuration and Prometheus metrics
- you want a Go-based server deployable via Docker or Helm on Kubernetes

## When to avoid
- you need a modern chat protocol like Matrix instead of XMPP
- you require extensive XEP coverage comparable to Prosody or ejabberd
- you need a managed messaging service rather than self-hosting
- you need very recent development activity, as releases have slowed

## Facets
- artifact type: service
- maturity: maintenance
- function: http-server, websocket, caching, monitoring, auth
- domain: self-hosted, iot, backend, networking
- platform: go, self-hosted
