Zed is totally open source, and the AI “features” are optional. When you set it up - at least when I did - it’s one checkbox to disable. I don’t remember about the telemetry you will have to have a look, I’m usually ok with that myself.

I came from VSCode and haven’t found anything I miss. I especially don’t miss the poor performance of VSCode, Zed is extremely lightweight!

That information about text editors is out of date - we now have Zed. Just ignore the “AI integration” bs, it’s entirely optional
