I wrote about this on my blog. I like the notion and points made here, but I also think we’re not helping by re-inventing things that already exist, so I’m torn on it. I have been happy with the existing one.

“new” == ~3 years old (but looking to move from alpha to beta in 2024 IIRC). It’s a good server!

At the moment it is explicitly designed as a single-user implementation, although I’m sure it could be pivoted to become multiuser. I’ve simply set up my own on Glitch and it is working great! -> https://pipesmarks.glitch.me/
