What’s that one tool you’re constantly Googling?

I started this project because I was sick of having 20 tabs open just for basic dev tasks. I’ve added the tools I use daily, but I know everyone’s workflow is different.

What’s the one utility you find yourself searching for five times a day? If it’s missing from Devutils.lol, drop a comment. I’m looking to ship the next few features based entirely on what you guys actually need, not just what I think you need.
