# agario-client: reconstructing the earlier agar.io client protocol

> agario-client is a Node.js implementation of an earlier agar.io client protocol. It connects over WebSockets, parses game packets, and provides API methods for movement, spawning and spectating alongside events for ball-state changes. The author stopped development after a later game update changed the client implementation.
