ONL JSDraw requires ?? an open internet connection; due to this, total file size is undetermined, offline use is impossible, and future stability is unreliable.
Ketcher has extra features if server scripts are installed. It might be easy to internationalize.
jsMolEdit (or jsMolEditor) development was stopped and moved into jchemhub, which later became Kemia.
