Gforth and pForth [0] are the usual Free and Open Source go-to Forths. Gforth is quite good at pointing out silly mistakes in your code. Unfortunately Gforth doesn't have great Windows support, and neither of them have very strong FFI. There are a number of proprietary payware Forths for desktop/server: vfxForth, [1] SwiftForth, [2] and iForth. [3] There are also various Forths for all sorts of embedded platforms, many of them FOSS.
