Best Markdown Viewer for Mac (2026)
An honest comparison of the macOS apps that render Markdown — for reading it, not writing it. We weighed price, whether they add a Finder Quick Look preview, live reload on save, Mermaid and math, and whether they lock you into a subscription. Facts verified June 2026; vendors change — tell us if something is out of date.
Short answer: if you want to read Markdown with Quick Look, a table of contents, instant find and live reload — for a one-time price, no subscription — Markdown Better View ($9.99) is the pick. MacMD Viewer is a solid alternative at $19.99; QuickMD is the best free standalone viewer; the free Quick Look-only utilities are great if all you need is a Finder preview; and Marked is for writers who export, not readers.
| App | Price | Type | Quick Look | Live reload | Mermaid · math | Subscription |
|---|---|---|---|---|---|---|
| Markdown Better View | $9.99 once | Viewer (+ live preview) | Yes + thumbnails | Yes | Yes · Yes | No |
| MacMD Viewer | $19.99 once | Viewer | Yes | ? | Yes · Yes | No |
| QuickMD | Free | Viewer | ? | ? | Yes · Yes | No |
| Marked 3 | $2.99/mo · Marked 2 $14.99 once | Previewer (writers) | No | Yes | Yes · Yes | Yes |

“?” = the vendor doesn’t clearly state it. *QLMarkdown’s Homebrew cask is deprecated (unsigned, fails Gatekeeper). †Glance’s original is archived and was removed from the App Store; only a community fork is maintained, and it’s unsigned (needs a Gatekeeper/quarantine workaround).
Full reading apps
Markdown Better View ($9.99, one-time) is built for reading: open any
.md and it renders instantly, with five themes and real dark mode, a table of
contents with scrollspy, instant find, a distraction-free reading mode, and folder→native tabs.
It ships a Quick Look extension and thumbnails, renders KaTeX math and Mermaid, and live
reloads on save — so it also does the previewer’s job. Sandboxed, no tracking, no subscription.
MacMD Viewer ($19.99, one-time) is a tidy SwiftUI viewer that also ships a Quick Look extension and renders Mermaid and syntax-highlighted code. It’s a good choice if you don’t mind paying roughly double for a similar reading experience.
QuickMD (free, App Store + Homebrew) is the strongest free standalone viewer: custom themes, native tabs, a recent-documents sidebar, LaTeX and Mermaid, and PDF export. If your budget is zero and you don’t specifically need a Finder Quick Look extension, start here.
Quick Look-only utilities
Anybox Markdown Preview ($2.99), PreviewMarkdown (free) and
QLMarkdown (free, open source) add a Finder Quick Look preview for
.md files. They’re great when all you want is to press Space in Finder — but they’re
not standalone reading apps (no table of contents, find, reading mode or tabs), and QLMarkdown’s
Homebrew cask is deprecated because it isn’t signed/notarized. Glance (free, open
source) previews many file types via Quick Look, Markdown included — but the original was archived
and pulled from the App Store; only a community fork is maintained, and it’s unsigned, so you have
to bypass Gatekeeper (a quarantine workaround) to install it.
A writer’s previewer
Marked is excellent, but it’s a different tool: a live preview that pairs with your editor, with heavy-duty export (DOCX, EPUB, RTF), proofreading and writer tooling. Marked 3 moved to a subscription. If you write long documents and export, choose Marked; if you mainly read, a viewer fits better. See our deeper take in Markdown Better View vs Marked.
The verdict
For the most common job — reading Markdown (AI agent output, READMEs, notes, docs) with Finder Quick Look and a real reading experience — Markdown Better View is the best balance of features and price: a full viewer plus Quick Look, thumbnails and live reload, for a one-time $9.99 with no subscription. Pay more for MacMD if you prefer it, go free with QuickMD or a Quick Look utility if features matter less, and pick Marked if you’re a writer.

FAQ
- What is the best Markdown viewer for Mac?
- For reading Markdown — not editing it — with Finder Quick Look, a table of contents, instant find and live reload, Markdown Better View is the pick at a one-time $9.99. MacMD Viewer is a capable alternative but costs about twice as much; QuickMD is a good free option if you do not need a Quick Look extension; and the free Quick Look-only utilities (Anybox Markdown Preview, PreviewMarkdown, QLMarkdown) preview in Finder but are not full reading apps.

- Markdown Better View, MacMD Viewer, Anybox Markdown Preview, PreviewMarkdown and QLMarkdown all add a Finder Quick Look preview for .md files. Markdown Better View and PreviewMarkdown also add rich thumbnails. Marked does not ship a Quick Look extension.
- Is there a free Markdown viewer for Mac?
- Yes. QuickMD is a free native viewer with themes, tabs, LaTeX and Mermaid. QLMarkdown and Glance are free open-source Quick Look generators (note QLMarkdown’s Homebrew cask is deprecated because it is unsigned).
