UI Designers → Figma is the forge. They can stay there from sketch → prototype → handoff.
Developers → coding is fragmented: editors, build systems, package managers, linters, formatters, version control, deployment, monitoring, etc.
There is no single forge.
The UI design example might be a little off, but it actually "lets you" to deliver a whole project without needing to keep different apps, tabs, windows open.
The goal is to bring at least a few things to one single focused platform. AI is writing most of our code anyway. So the thing we must focus is may not be "writing code", it's "reviewing code" and doing refactoring.
Zed is perfect. I'm using it. But I find their development speed rather slower, since they do most of the things from scratch, even their own GUI library. When are they going to ship on mobile or on web? God knows.
But they're simply perfect. I'm inspired by them. You can follow the agent when it's working on your codebase. You can view all the warnings and errors in one vertical view. It's blazingly fast and literally beautiful.
I'd like to dream one app though, it works on everywhere, opinionated, convention over configuration. And that is Athas Code Editor.
