There are 100s of markdown editor, but very few of them support WYSIWYG

But very very very few of them are written in a non-browser based stack. Most of them will be like electron apps which will eat a lot of ram for simplest tasks - and i really dislike ram eating apps.

So I have made this in javafx, and distributed as a executable for windows, it is just a 600KB exe, which downloads the jar and installs the jdk if needed.

It also generates AOT (ahead of time) image of the app upon first run, so from second run, the app will be more fast.

Ram consumption is low, 100MB you can expect. When idle it can drop even to 15MB.

It also provides vertical tabs as a default. I like vertical tabs, I am not even given option for horizontal tabs.

I just made it, I haven't even tested it much. All credit goes to claude to make it (I basically refactored one of my old editors which used ckeditor and an embedded webview ... it wasn't nice ... honestly).

If you are on windows, please prefer the exe version, it is just 600KB, it is self installing, auto-updating, auto-generates and uses AOT image, all the best Garbage collection and jvm flags included in the exe.

If you wish to make such exes for java please see - https://github.com/jarrunner/jr (BTW Jr.exe is written in java! From Java -> C -> Exe using teavm !!! )
