Choose a Markdown app
The best Markdown viewer fits the way you work.
A good Markdown app should solve the job you actually have. Choose an editor when you spend most of the time writing syntax. Choose a dedicated viewer when you want fast, accurate reading, Finder previews, and a clean window beside your editor.

Start with reader or editor
Markdown editors optimize the source-writing loop. Viewers optimize the finished document. If you already write in Cursor, VS Code, Zed, Vim, or another editor, a separate viewer can provide a calmer reading surface without replacing your tools.
Choose an editor
Best when formatting controls, source editing, and document creation belong in the same window.
Choose a viewer
Best when you want fast opening, faithful rendering, live reload, outlines, search, and distraction-free reading.
Use both
Keep your preferred editor on one side and a viewer that follows every save on the other.
Check the Markdown you actually read
A basic renderer may be enough for prose. Technical documents often need GitHub-flavored tables and tasks, highlighted code, local images, Mermaid diagrams, and KaTeX maths. Test a real file rather than relying on a generic feature list.
Look beyond the main app window
A useful Mac viewer should fit Finder and file workflows. Quick Look can turn the Space bar into the fastest way to inspect a .md file, while default-app registration makes double-clicking predictable. Tabs, find, outlines, print, and PDF output matter for longer reading sessions.
Decide where your documents may go
Online viewers are convenient for disposable text, but private plans and repository documents may not belong in a browser service. A local viewer with bundled rendering can work offline without an account or a document upload.
Choose Imark for reading and review
Imark is a strong fit when you already have an editor and want a free, open-source Markdown viewer for Mac with Quick Look, live reload, Mermaid, KaTeX, and comments stored inside the file. It is not designed to replace a full Markdown editor.
