Quikdown – 17 KB bidirectional Markdown parser and rich-fence editor

Quikdown is a tiny (~17 KB, zero-dependency) Markdown parser and bidirectional split-view editor that lets developers edit either the Markdown source or the rendered output and get Markdown back. It’s built for developers who need a lightweight, embeddable editing tool without heavy frameworks, and it’s interesting because its bidirectional sync and rich-fence support pack unusual functionality into an exceptionally small footprint.
