Lively Kernel is a Smalltalk-like environment that runs in the browser. It might be better for that server-side stuff than normal Smalltalk.
Unfortunately, it’s written in JavaScript, which is not a good language, but I think it can also compile ClojureScript, which is much better. Cloxp is a related project that’s more Clojure-based.
Amber Smalltalk also runs in-browser. The maintainer has kind of gone off in a weird direction, but it still works. PharoJS was supposed to be an alternative with a different approach, but I’m not sure if it was ever completed.
Emacs is the closest Lisp has to a Smalltalk environment. There are emacsen written in other lisps, like EdWin and Hemlock. These can be run in a terminal over ssh.
