Rhun shares an x86-64 assembly core across platforms with a build-time ARM translator

rhun.app Editor score 6/10

Rhun’s editor and pixel renderer use an x86-64 assembly core, translated to AArch64 at build time for Apple silicon. The early solo project offers an unusual cross-platform implementation approach and includes panels for coding agents.

What

Rhun is a small, fast code editor written in assembly and available for Windows, Linux, and macOS.

How

It combines editing features with a terminal, Git tools, and optional coding-agent integrations beside the code.

Why it matters

Engineers can run builds and shell commands in the editor while keeping AI assistance optional.
