DevTools for productivity

This may sound crazy, but developers are lazy. I know, unbelievable. Some of us are, we need to automate lots of our tasks because repetition can be tiring. So let me show you some tools I find extremely useful, either because they make my life easier or because they push me to write more accessible code.

We've all done it. Type ls you lazy, lazy person !

These tools will either be browser/IDE extensions, web apps or CLIs.
