About
Built by a player, for players
Agar Sandbox started as a private practice server and grew into a full training tool.
What it is
Agar Sandbox runs real game servers on your own computer, so you can practice without other players, lag or losing your mass. You can pause the world, save a moment and rewind to it, move cells by hand, and load drills that put everyone exactly where they need to be.
Who makes it
Agar Sandbox is made by Sena (Discord @senamom). Add a few lines about yourself: how long you've played, what you play, why you built this.
What I care about
- Practice that's actually useful. Every drill starts from a real situation you'll see in a game.
- Simple to use. Install it, enter your key, play. No browser scripts.
- Listening to players. New drills and features come from what the community asks for.
