I was compelled by the original release of Zed:
Zed is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.
Atom was a pretty darn fine code editor, only scuttled by the fact that Microsoft bought GitHub back in 2018. Atom was GitHub’s thing, and Microsoft already had VS Code.
At the heart of a code editor is an extremely strong code parsing tool and that’s exactly what Tree-sitter is. Plus you can tell they are making polished design a priority. Now that Zed is open source, it bodes well. The FAQ says they plan to work on extensions after it’s open sourced. That seems prudent, as I suspect the average VS Code user has ~15 extensions customizing things and making it work well for their exact dev environment.
