Show HN: Rhun, an open-source code editor written in assembly

Developer vshvedov released Rhun v0.16.2, an open-source code editor written in assembly, available for Linux and macOS via a curl install script and for Windows as a ZIP download. Rhun offers tabs, syntax highlighting, fuzzy search, optional Vim mode, 39 light and dark themes, and built-in diff review, staging, and commit, with optional AI features that run local open-weight models or Claude Code and Codex using existing subscriptions. The editor is positioned as a lightweight alternative that keeps AI assistance optional while letting users follow Claude Code and Codex sessions beside their code.
