## What it is
roBrowser is a free, open-source web-based implementation of the Ragnarok Online MMORPG client, written from scratch in JavaScript using WebGL, HTML5, and the File API. It connects to existing Ragnarok Online game servers from the browser and includes tools for viewing and extracting game files such as maps, models, and textures.

## Use cases
- play ragnarok online in a web browser
- host a browser-based client for my ragnarok online server
- view ragnarok online maps and 3D models in the browser
- extract and browse GRF game archive files
- convert ragnarok online game assets like BMP textures to PNG
- run a game client without installing the original executable

## When to choose
- you run a Ragnarok Online server (e.g. rAthena or Hercules) and want a browser-based client
- you need to inspect or extract Ragnarok Online game files, models, or textures
- you want a cross-platform client that doesn't require installing the original game executable

## When to avoid
- you want a complete, bug-free game experience - the project is not a stable release
- you need active development or recent updates - the latest release dates from 2017
- you want to play on official Gravity servers rather than private servers
- you need a game that works without original client files and a separate game server
