Open Source Forth Systems With First Class Preemptive Multitasking?
Zeptoforth has this, but it’s for embedded systems. https://github.com/tabemann/zeptoforth

which forth do you guys use for normal day to day scripting and programming
I am the developer of zeptoforth, which is the main Forth I am using at the present. It supports the RP2040 (particularly the Raspberry Pi Pico, but it should work on other RP2040 boards), which I have been working with lately, and the STM32F407, STM32L476, and STM32F746 DISCOVERY boards. Note that it is not a desktop Forth; for that I would probably just recommend gforth.

x-in-y lines - Succintly written (<1000 non-obfuscated loc), fully-functional software in any language.
almost all my codes in https://github.com/phreda4/r3 and https://github.com/phreda4/r4 have less 1000 lines, but all forth have code with minimun lines of code

r4 Forth
Looking here I think they've made the decision to go with the MIT licence.

Share cool Forth programs!
I wrote many programs in r4 (32 bits windows).. see in https://github.com/phreda4/r4

r4 is for 32bit https://github.com/phreda4/r4

Looking for a simple forth compiler (producing asm/executables, not compiling forth words) to learn from, preferably in C family language
I have a vm in c for my forth, I have a compiler to asm (generate FASM output) but in the same lenguage, really a forth compiler is a simple program, there are a 1:1 correspondence in code genaration and words. here the 32bits source https://github.com/phreda4/r4/blob/master/r4/System/r4i86.txt here the 64bits with some optimizations: https://github.com/phreda4/r3d4/blob/master/r3/sys/r3asm0.r3 I hope this help
