Does Agar.io Personal Toolkit bypass anti-cheat?

No. The toolkit uses transparent client-side input helpers and overlays. It does not inspect private traffic, spoof sockets, automate accounts, or play unattended.

How do I install the Tampermonkey version?

Download the minified userscript, open Tampermonkey, create a new script, paste the file contents, save, then reload https://agar.io.

Which browsers are supported?

The extension targets Chromium-based browsers including Chrome, Brave, Edge, and Opera. The userscript build targets Tampermonkey.

Polished controls without unsafe game manipulation

Agar.io Personal Toolkit focuses on client-side input helpers and readable overlays. It avoids bots, account automation, packet spoofing, private traffic inspection, and hidden behavior.

Fast personal hotkeys

Hold W for Extra Feed, press A for Double Split, press Q for Triple Split, and press S to toggle stop mode.

Lightweight overlays

Use a compact control panel, mini-map estimate, FPS/ping strip, and brief lag warnings with safe latency fallback.

Transparent by design

No bots, no farming, no private traffic hooks, and no hidden behavior. Every feature is visible and configurable.

A safer Agar.io extension for hotkeys and overlays

This Agar.io extension is designed for players who want faster personal controls, clearer on-screen information, and easy configuration without turning the game into unattended automation. It supports Chrome, Brave, Edge, Opera, and Tampermonkey.

What it does not do

It does not bypass anti-cheat systems, read private server traffic, spoof sockets, farm accounts, or run a bot. Advanced game state such as exact positions only appears when safely available from client-rendered state.
