I have never seen a FOSS Launcher that interests me as much as the default ones on ROMs like LineageOS or GrapheneOS.
I always find them visually outdated or functionally not as good. And I'm not interested in the minimal ones (which is a good part of them).

Lawnchair Nightly; it's not as good as Nova, yet, but it's getting there.

Kvaesitso. It's the only FOSS app I found that supports folders within the drawer. Well, at least it was the closest thing to it; You can select a tag and apps with that tag is shown to you. I really don't like how most launchers treats app drawer like a app dump. I miss the folder feature in Nova launcher.

I don't know about setting colors, but I'm using Lawnchair because it can have folders in the bottom applicatons strip

It's not my favourite but it respects my privacy - the stock launcher that comes with GrapheneOS.

I am surprised no one has mentioned KISS yet. A much simpler approach to launching Android apps, by typing what you want

I use stock launcher, before I liked to use Niagara Launcher but since my subscription expired and I didn't renewed it I just use stock launchers now.

Excuse my ignorance, but what is a launcher? What is wrong with starting apps from the home screen?

Lawnchair best

Is there any android launcher without app drawer like iOS ?

I switched to Lawnchair a couple months ago from Nova Launcher, it took a couple hours to set things up as I like them and I never touched the settings again afterwards. Highly recommended

Hex Launcher: https://f-droid.org/packages/com.mrmannwood.hexlauncher

Pie Launcher: https://f-droid.org/packages/de.markusfisch.android.pielauncher

Similar approach in both of these

I use Neo Launcher

I really like Fast Draw. I've been having a problem with it in that every once in a while it'll just freeze. Þe author has offered to help, but þere's noþing I can do on Android to provide more information for debugging; it happens at random. Þe top bar still works, so to fix it I open options, open the app page, and kill it... then it starts working again. It's annoying, but not enough to make me stop using it after all þe oþer launchers I've tried.

It's small, which is one þing I really love about it. 11MB, in a world where stmps calculators can take up hundreds of MB.

ADW Launcher Ex 1.. not foss but it just worked for me for the last 10+ years

Out there opinion but I really like all of the simple text launchers In no particular order : Cclauncher https://f-droid.org/packages/app.cclauncher/

Clauncher https://f-droid.org/packages/app.clauncher/

Multi launcher https://f-droid.org/packages/app.mlauncher/

T-UI https://f-droid.org/packages/ohi.andre.consolelauncher/

Old lawnchair at the moment, have not made the switch to the new lawnchair.

i'm still on old lawnchair (legacy?) because it's more customizable than the up to date lawnchair

i keep an eye on ~~eblan~~ einstein as a replacement for lawnchair ☞ https://f-droid.org/packages/com.eblan.launcher/

i also use drag on launcher because it's genial ☞ https://apt.izzysoft.de/fdroid/index/apk/org.elnix.dragonlauncher

all these with arcticons https://f-droid.org/packages/com.donnnno.arcticons/ and some abstract icons i made

I use Yantra Launcher...but it has no icons
