Small tools and experiments built at Web Experts, free to use and free of sign-up forms. Each one started as a question worth answering and turned into something worth handing to other people.
Nothing here is a product or a funnel. There is no email gate, no trial, and no upsell waiting at the end. If a toy proves useful it stays up and gets maintained, and if it stops earning its keep it comes down. Open one and see what it does.
Every prompt you type into an AI burns energy, water, and carbon somewhere in a data center. Web Experts built Token Print to put a number on it: a free, cited calculator that estimates the footprint of your AI usage, in English or Spanish, no email required. Tell it what you use AI for and how much, and it shows you the real cost in energy, water, and carbon, with sources for every number. Built by the same people who make this site, because knowing what a thing costs is the first step to using less of it.
Free music radio built on Bluesky and the AT Protocol. No sign-in needed to listen and no tracking. The stations are live queries over the network, not playlists, which means the sound changes as the people on Bluesky post. A Web Experts experiment in what open social data can make.
