## What it is
OpenFront.io is an open-source online real-time strategy (RTS) game focused on territorial control and alliance building, playable in any modern web browser. The repository contains the full TypeScript client and server code, forked from WarFront.io.

## Use cases
- play a browser-based RTS game about territorial expansion
- self-host an io-style real-time strategy game server
- contribute to or fork an open-source multiplayer RTS
- study how a browser RTS client-server game is built in TypeScript
- run a strategy game with real-world geography maps

## When to choose
- you want a free, open-source browser RTS you can play or self-host
- you want to modify or extend an io-game style real-time strategy
- you need a TypeScript example of multiplayer browser game architecture

## When to avoid
- you need a polished, production-stable commercial game (it is labeled ALPHA)
- you want a native desktop or mobile RTS rather than a browser game
- you need a game engine or general-purpose framework rather than a complete game
