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