Not sure if this counts, but I'll throw my own project (semi-CLI-driven testing framework) into the ring, not as a perfect example overall, but as an example of what I wish more projects did, which was let me experiment a bit with their interfaces before I downloaded them. This isn't something that's doable for every utility, but especially with the advent of WASM and easier cross-compiling from C, I wish more CLI/API documentation would allow me to play around with examples or try out a command on their docs page or in a sandbox; particularly if they're selling themselves as having a composable interface. That's not only helpful for figuring out whether or not I want to use the project, it's also helpful when I look at a piece of documentation and am not sure which flag or option is actually important. https://distilledjs.com https://distilledjs.com
