Excelsior guy here. Actually, Excelsior JET is a proper AOT compiler. That is, a developer or build enginer runs it on their workstation (build server) and then ships a native executable to the end users. We used to have a caching JIT, and even an option to recompile the cache into a single binary, but concluded it is not worth the hassle, and deprecated it last year.
