Forth is known for extremely compact representation of code, and very portable, because standard have very few registers and work on stack machine. Unfortunately all these at cost of slow execution and not easy to make serious projects (hard to deal with large codebase chaos, but read more). So it definitely, platform for slow embedded applications, keyword Arduino, may be Raspberry. Sure, compactness is huge advantage in some other cases, for example, known boot loader shell for UEFI is written on Forth, so you could write applications for it (and yes, for this use case any modern motherboard except Apple). For large codebase works, some Forth people learn Scheme and technically switched to Lisp programming paradigm. Yes, it interest phenomena, Lisp techniques work with Forth good enough if developer disciplined enough. Sure, Lisp will open for you whole new world.
