I have ben using playcoee for about a year now primarly to do some quick coding of javascript code to do some debugging as it takes too much time to create a new project locally to do testing, likewise have been doing motion effects using css within this tool to save time opening vs code and creating new file, this tools has been a wonderful asset and hope it gets better close to codesandbox.io, just hoping there would be a way to use my local core to upload and use npm install to do some check. Overall I would definitely recommend this tool for developers and the ones who want to learn development!
