I saw this project before, and it reminded me of a toolbox I used to create, which included some simple open-source tools. Later on, I turned it into my own bookmarks, and then when I moved my blog to cf, the toolbox was closed. When I saw this project, I really wanted to rebuild it and continue collecting.
However, unfortunately, it seemed that I was also tinkering with other things at the time, so I didn't get around to it. Then I thought about having to worry about the server's running status and not having enough time to indulge myself, so I gave up.
Now, out of boredom, I'll bookmark this project. I remember seeing the preview link: https://www.autopiano.cn and I listened to it for a long time.
