I saw this project before and it reminded me of a toolbox I made earlier, which included some simple open-source tools. Later on, I turned it into my own bookmark and then hosted my blog on cf, so the toolbox was closed. When I saw this project, I really wanted to rebuild it and continue collecting.
However, unfortunately, it seemed like I was also tinkering with other things at the time, so I didn't go for it. Then I thought about worrying about the server's running status and not having so much time to cultivate my sentiment, so I gave up.
Now, I'm bored and just bookmarking this project. I also listened to it for a long time on the preview address: https://www.autopiano.cn.
