Summary

Rhun is a small, fast, open-source code editor written in assembly, offering tabs, syntax highlighting, fuzzy search, Vim mode, and an optional AI coding agent across Windows, Linux, and macOS.

I found that I&#x27;m not using even 1&#x2F;3 of vim&#x2F;vscode features anymore.<p>That&#x27;s wht I&#x27;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.<p>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.<p>It&#x27;s a solo project, MIT licensed and still early.
