JWasm ended in 2014. New versions are available as projects ASMC or UASM on GitHub.

Great tool. I was finding a compiler for old dos and this works very well. It's good to know this works with x64 as well.
-
Very good alternative to masm and tasm in most cases.

Great job!

A very good alternative to Masm, and a lot faster. Almost fully compatible, the remaining 0.1% are in the bugs list; before embarking on a bigger project, study that list, although usually these bugs have no relevance for the average user ;-)
