READMEs, notes and docs. Colored headings, links and code in the editor, a live rendered preview next to it and a heading tree on the left.

Loper is a free, minimal editor for macOS that opens Markdown instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
