Kakoune is a code editor heavily inspired by Vim, as such most of its commands are similar to Vi's ones, and it shares Vi's "keystrokes as a text editing language" model. Kakoune has a strong focus on interactivity, most commands provide immediate and incremental results, while still being competitive (as in keystroke count) with Vim.

Jupp is the portable version of JOE’s Own Editor. It has been enhanced by functions intended for programmers or other professional users. It comes with the editor flavors known from joe, specifically, jmacs, joe, jpico, jstar, and rjoe.

Jed is a powerful programmer's editor using the S-Lang scripting language for configuration and extensibility. It provides emulation modes for the key bindings of many editors (including Emacs and WordStar), and has syntax highlighting for dozens of languages. Jed is very small and fast.

The edlin program is a small line editor, written for FreeDOS as a functional clone of the old MS-DOS program edlin.

L3afpad is a GTK+ 3 text editor that emphasizes simplicity. As development focuses on keeping weight down to a minimum, only the most essential features are implemented in the editor. L3afpad is simple to use, is easily compiled, requires few libraries, and starts up quickly. L3afpad is a fork of Leafpad that uses GTK+ 3 instead of GTK+ 2.

Lem is a Common Lisp editor/IDE with high expansibility.

A Kakoune / Neovim inspired editor, written in Rust.
