Kod is an open, modern text editor project for programmers on Mac OS X, built with the idea of being a versatile everyday tool for writing code and plain text. The project’s design philosophy emphasizes approachability and a relatively low barrier to entry, including UI concepts like tabs as a core part of the experience. Beyond being “yet another editor,” Kod aimed to explore how a programmer-oriented editor could feel more universal and user-friendly, especially for people who write code but don’t necessarily want an overly complex environment. The repository contains the full editor codebase and related components, but it is also clearly marked as an archived (read-only) project, indicating it’s no longer actively developed. Even so, it remains useful as a reference implementation for macOS editor architecture, UI/editor interaction patterns, and the tradeoffs involved in building a full desktop editor.
