Earlier quoted context omitted.
Compared to Sublime Text: RAM: 213 MB Zed 41 MB ST Storage: 406 MB Zed 52 MB ST Startup time: Zed is slower than ST (but only by a few milliseconds). Also when you reopen ST it will remember how you've resized the window from last time whereas Zed won't.
ST is a text editor while Zed is an IDE. I wish there were something like VSCode that is very modular but written in native. But VSCode is good enough and it is my daily driver.
I disagree Zed is an IDE, it is quite far from InteliJ, Borland/Embarcadero, VS, XCode, Eclipse, Netbeans...
If it is about adding enough plugins until it eventually becomes one, then any programmer's editor is an IDE.
