rhun: a small, fast code editor written in assembly

About

I found that I'm not using even 1/3 of vim/vscode features anymore.That's wht I'm building rhun - a small code editor for Linux, Windows and Apple silicon Macs. It obviously has Vim mode, a terminal, Git diffs and a panel for Claude Code or Codex sessions.The editor and pixel renderer share an x86-64 assembly core. For Apple silicon, a build-time translator converts that core to AArch64, with separate platform adapters around it. The latest release can draft commit messages using a local Ollama model or an existing Claude Code or Codex subscription.It's a solo project, MIT licensed and still early.

small and fast sounds good, but what's the pricing and how does it compete with existing editors?
