About Kyun

Kyun is a terminal text editor written in Rust, described by its author as "the worst text editor (yet)." Its stated focus is deliberately low productivity, low fidelity and low customizability, with the discomfort of the editor treated as a feature; it is designed for writing cutesy, "uwu-style" text. The project presents itself as cross-platform and says it has been tested on UNIX (specifically Arch) and Windows, while macOS and Free/Net/OpenBSD have been confirmed as working by others. It can be installed with cargo or by downloading a release, and it is based on another text editor by Philipp Flenker licensed under CC BY 4.0.
