A small code editor for Windows, Linux and macOS. Written in assembly, with a built-in terminal, Git diffs, fuzzy search, Vim mode and a panel for Claude Code and Codex sessions. Free and open source.
I found myself using less of my editor as coding agents took on more of the work. I still wanted to read the code, make edits, run commands and check the diff.
rhun keeps those things close together: an editor, a terminal, Git and a panel for agent sessions. It is written in assembly and runs on Windows, Linux and Apple silicon Macs.
It is early, free and MIT licensed. Try it on a small project and tell me what gets in your way.
I added commit message generation in the latest version of rhun. You can use a local LLM through Ollama, or your existing Claude Code or Codex subscription via their CLI.
Local model setup is built into the settings. Generate a draft from your diff, edit it, then commit when you're happy with it.
respect for the flex but genuinely curious how this stays maintainable long term. cross-platform assembly means three separate codebases under the hood, not one, and on top of that you're shipping vim mode, git diffs, a terminal and an agent panel. every feature request is now times three to build and times three to debug. what's the actual team size behind this, and does the small-fast-editor promise survive year two of feature creep?
