Muzli chrome extension: great inspiration sourced from the best design media publications (i.e. Design Milk, Dribbble, Abduzeedo, Behance, etc.) all organized as a chrome extension.
WhatFont: to creep on other people’s stuff and get their dope fonts
Dimensions: sometimes you need to check the dimensions of a page. Super important for web dev just to make sure you don’t mess up a pixel somewhere.
Responsive Web Design tester: I once designed a screen for a 15” computer, my developer made it for 13” screen, it didn’t end too well.
Motivation: just a little fun bonus chrome extension. Give it a try and see why it's called Motivation 😉
