Mac: Alfred 2 is a fantastic way to automate your tasks and launch apps on your Mac, but you don't necessarily have to put in the legwork to create those workflows yourself. Github user Zenorocha has compiled a massive list of web developer-specific workflows to get you started.
Zenoroch's list varies from searching for fonts on Font Awesome to several Github specific tricks. One of the handiest on the list is quick way to search for answers on StackOverflow. Zenorocha's list is pretty specific to web developers, but everyone else can also check out this list of workflows if that's not your bag.
