Lively also got some influence from Emacs in terms of integrating tooling and support for remote development. One example, connecting to another webpage and modifying it via lively: https://www.youtube.com/watch?v=gbp30e_QYvY. Apart from JavaScript, it is easy to integrate other languages as well, e.g. you can connect to a running Python process via https://github.com/LivelyKernel/lively.py) and then use workspaces and file editors inside of Lively to modify and run Python code. This stuff is based on a generic RPC mechanism that connects Lively worlds and other runtimes: https://lively-web.org/users/robertkrahn/2015-06-12_l2l-map.....

cloxp is following more a traditional Smalltalk-model, the core component is a system browser for Clojure namespaces.

If you want to run it locally via https://github.com/LivelyKernel/lively.installer then it should run well in MacOS and Linux. On Windows you might need to use a proper bash (e.g. git bash or the Ubuntu subsystem).

There is a desktop app for mac os that wraps the installer and gives you a menu bar entry for controlling the lively server but in the end it is just a frontend for what the installer does.
