You joke and folks downvote, but this is my biggest issue with WebStorm. I'm seriously considering switching for the first time in 16 years. Zed is quite snappy. The Claude Code integration in VS Code is brilliant. I've used the CLI in the JetBrains terminal. I had no idea I could revisit past conversations until I used the VS Code extension!

Zed is snappy in the same way that notepad ++ is snappy: If you don't support 10% of language features you can avoid the hard work. Unfortunately this means that non trivial projects have false positive errors everywhere.

Is that why they've given up on their own C++ analyzer and finally adopted clangd?

Zed uses clangd, I don't think clangd support only 90% of C++ (and I don't think it avoid hard work).
