If there is something, I haven’t really encountered it yet. I love emacs for julia development and see no reason to change. I mostly use emacs-jupyter in org notebooks as essentially a REPL / scratch space with better history support and then I use Revise.jl to hot-reload code in .jl files that I’m working on.
If you prefer using julia’s built in REPL, then check out julia-repl.
For things like interactive plots and other fancy graphical things that don’t play nicely with emacs, I just use Blink.jl together with Interact.jl to spawn electron windows where I make little GUIs and put interactive plots.
Long live
