OctoPrint
It seems I'm the minority here, but I dont like OctoPrint. My main issues:- Terribly slow startup and load times.- no support for mobile devices just with some app.- While it can do lots of things with plugins they tend to kill performance which might cause artifacts on the print.- slow on updates, they ware on Python 2.x until this year.I'm currently migrating to mainsail (https://github.com/meteyou/mainsail), which looks much better.
