The focused, native macOS markdown viewer you've been waiting for.
Epic MD Viewer opens .md, .markdown, and .mdx files instantly — under 500ms — and renders them beautifully using GitHub Flavored Markdown. It lives alongside your editor as a dedicated, always-in-sync preview window.
Live Preview That Keeps Up With You Save in VS Code, Cursor, Zed, or any text editor — Epic MD Viewer detects the file change and re-renders in under 200ms. Your scroll position is preserved. No refresh button needed.
Full GitHub Flavored Markdown Headings, tables, task lists, blockquotes, footnotes, inline HTML, autolinks — all rendered correctly using cmark-gfm, the same parser GitHub uses internally.
Mermaid Diagrams — Offline Flowcharts, sequence diagrams, class diagrams, state machines, Gantt charts, pie charts, git graphs, mindmaps, and timeline diagrams. All rendered as crisp SVG using bundled Mermaid.js — no internet required.
Syntax Highlighting in 20+ Languages Swift, Python, JavaScript, TypeScript, Rust, Go, Ruby, Shell, JSON, YAML, TOML, HTML, CSS, SQL, Kotlin, Java, C, C++, C# — with a light theme in light mode and a dark theme in dark mode.
Document Outline Jump to any section instantly. The outline sidebar extracts all headings and updates live as you reload. Click any entry to scroll there with a smooth animation.
True Native macOS Built with Swift, SwiftUI, WKWebView, and NSDocument. Respects macOS conventions: drag-and-drop, Open Recent, keyboard shortcuts, and full sandbox compliance. No Electron, no background processes, no telemetry.
