Since Eaglercraft runs in a browser (JavaScript/HTML5), "hacked clients" are essentially modified versions of the game or external scripts that add features not found in the vanilla version. These features typically include: : Fly, Speed, Spider (climbing walls), and Step. : KillAura, AutoClicker, and Reach. : X-Ray (seeing through blocks), Tracers, and ESP. : Auto-Eat, Chest Stealer, and Fast Place.

Some hacks use a "Javascript Bookmark" that, when clicked, injects a cheat menu into an active Eaglercraft tab. 1.8.8 Hacked Client Eaglercraft
