I’ve switched from Nova Launcher (after their aquisition) to lawnchair launcher and it’s been a good replacement for me. Similar feature set and I’m not really missing much, so I’m fine with the slow development.

I am currently using Kvaesitso

Quite active development, but without a classic home screen

Lawnchair hasn’t made me want to move in years

I switched to Olauncher (F-Droid) half a year ago. It’s a minimalistic clutter and distraction free launcher that feels like finally getting the control back over your smartphone usage.

Shade Launcher. It’s a bare bones Open Source launcher, while having a traditional look.

I use Launcher, which is as minimal as its name.

No widgets. No icons. The screen is just the current time. You swipe or tap to get an app drawer, or launch an app or shortcut. Very customizable. Very minimal.
