This is a comparison of ZZT editors. (Note: In MediaWiki it is possible to make “data-oriented” comparison tables by the use of templates; in DokuWiki this doesn't seem to work with any extension, all of them have problems that prevent it from working.)

The editors being considered are:

Others may be considered in future. (A proper review of the editors should be written, I hope.)

Also, the below tables are probably not very good; maybe someone knows how to improve them better.

A feature of frezed that allows you to use shortcut keys to access boards linked by edges and by passages, and allows setting both kind of links.
Some versions of KevEdit have such a feature; I am not sure about the official version.
Use an external text editor for ZZT-OOP codes
Only 8×14
Unlikely to be added; this should probably be better handled by external programs.
13) , 16) , 22)

I am not sure that it saves the world map; this footnote should be fixed by someone who knows

Frezed does not currently have an internal text editor; an internal text editor will probably be added in future.
ZZT treats a null character like #END; some editors may allow you to type them
Currently requires an external text editor (such as Vim, which can edit text with null characters); support in the internal editor will probably be added in future
