## What it is
Freeciv-web is an open-source turn-based empire-building strategy game playable in any HTML5-capable browser, with both a 2D isometric canvas client and a 3D WebGL client. It pairs a JavaScript/Java web client with the Freeciv C game server (patched for WebSocket/JSON) and a WebSocket proxy, supporting single-player against AI and multiplayer modes like Longturn and play-by-email.

## Use cases
- play a civilization-style strategy game in the browser
- host a self-hosted multiplayer turn-based strategy server
- play single player against AI opponents
- run longturn or play-by-email strategy games
- play a 3D WebGL strategy game in the browser

## When to choose
- you want a free open-source Civilization-like game playable in a browser
- you want to self-host a multiplayer strategy game server
- you want a game that runs without installing anything on the client

## When to avoid
- you want a native desktop game client with modern graphics
- you need real-time rather than turn-based gameplay
- you want a polished commercial game experience
