With Jetbrains you're paying for the IDE.

Zed's vision is that the editor is free and you're paying basically for Teams-lite.

If you're a big company, you're already using a service like Teams, Slack, Zoom, etc.

If you're a small company, then there's free alternatives like Discord.

And say you want to talk to someone other than a programmer, then you'd need something else anyway. Because a project manager wouldn't need an IDE installed.

But with Jetbrains products, you pay or the entire software, not just part of it .

Community edition is free, and it’s a sizable chunk of the entire product

The difference is, all the important features are behind a paywall. This will not be the case for Zed it seems.

I have never worked at a place that uses Jetbrains products which does not pay for their premium offering.
