From Hacker News:

Founder of Atom here. We're building the spiritual successor to Atom over at https://zed.dev.

We learned a lot with Atom and had a great time, but it always fell short of our vision. With Zed we're going to get it right. Written in Rust, custom native UI framework, engineered to be collaborative. Just starting our private alpha this week, so the timing of this announcement feels quite fitting.
