Most of the internet’s best tools never trend. They just sit there, quietly solving a problem, until somebody sends you a link and you wonder why you didn’t have this bookmarked years ago. Here are 50 of those sites, the ones that feel like a hidden toolbox: free research papers, a Photoshop stand-in in your browser, a place to check if your email got leaked, and a caf\u00e9 soundtrack when the house is too quiet.<\/p>\n\n\n\n

Each one is linked directly. A few have moved or changed hands, and I’ve noted those so you don’t hit a dead end.<\/p>\n\n\n\n
