## What it is
Wildfire IM is a professional-grade instant messaging and real-time audio/video solution with a Java-based IM server, push/robot/app servers, and native clients for Android, iOS, Web, desktop, and mini-programs. It uses MQTT+Protobuf with AES/SqlCipher encryption, supports fully private intranet deployment, super groups, channels, and VoIP conferencing, with a free community edition and paid professional edition.

## Use cases
- build a self-hosted chat app like WeChat
- add private instant messaging to an intranet
- embed a chat SDK into my mobile app
- deploy a private video calling and conferencing server
- run an IM server with group chat and channels
- replace cloud messaging services with on-premise IM
- support million-user online messaging with clustering

## When to choose
- you need fully private, controllable IM/RTC deployment without third-party dependencies
- you want cross-platform clients (Android, iOS, Web, desktop, mini-programs) out of the box
- you need high performance with low resource usage and optional clustering
- you operate in China or restricted networks and need robust connectivity and domestic-platform support

## When to avoid
- you need a fully open-source permissive license - parts are proprietary and the license is non-standard
- you lack in-house development capability for self-hosting and secondary development
- you only need a simple chat widget with no server infrastructure
- you want a hosted SaaS chat service with zero maintenance
