Any hobbyist native OS in the past for classic Amigas?

Oh, I really forgot about Arp-requesters. No I was refering to the ARP 1.3 CLI-commands. If you use their CLI-commands you have a non Commodore shell. And if you use Jazzbench you have a non Commodore Workbench. However Kickstart and all the libraries were the originals, so it really wasn´t the core of a OS, but most of the stuff the user actually sees.

That sounds very interesting, do you have any links to further info?

Debian 68k

Of course ther was NetBSD for all MMU-Amigas with 8MB of RAM in the 90s.

Not only was, but still is. Latest NetBSD release still does support 68k Amigas (though 16MB of RAM is minimum these days).

There's also experimental PPC-native version for Amigas with Phase5 CSPPC/BPPC cards, and it sort-of-works.

QDOS - Sinclair QLDOS replacement. It worked pretty well on my classic Amigas - full replacement of everything Amiga.
There is also Kick rom replacement with QDOS for UAE.

I just popped AmigaLibDisk 228 into my SAM:

    Welcome to my Workbench replacement program!  I haven't decided on a
    name yet, but I've tentatively named it JazzBench.

Interesting. Must try it soon.

My possible explanation for the number of hobbyist OS for the x86 was due to the fact that Windows was really crap these days and the number of x86 machines was a lot higher. And the Amiga needed no replacement for its wonderfull OS.

That's the point!
