Arduino IDE should be avilable for Chromebook

I have been searching and searching for how to program the AVR processors via Arduino. Some users says that i can use www.codebender.cc but i don't want to use that. I just want to install Arduino IDE, or a IDE who works smiliar as the Arduino IDE.

Am I bad updated that their is no Arduino IDE or a IDE smiliar as the Arduino IDE avilable for the Chromebook or is it avilable for the chromebook?
