Tabby seems to get a lot of hate in the comments here, but I enjoy it for the following reasons:
it looks consistently on all platforms
it has a nice working sync of connection profiles (even of ssh keys…encrypted!)
its opensource
Yes, it is built on electron-crappie, but for someone who jumps across different workstations with multiple hosts with their own configurations, tabby is very straightforward.
Could the sync be done with other means? Sure, but I won’t bother since tabby offers that OOTB and I can get up and running in 5 minutes from a fresh install.
