Markdown Prism – A Non-Electron Markdown Editor for macOS
Hi HN, I built a macOS-native Markdown viewer/editor called Markdown Prism. Website: https://prism.huconn.xyz GitHub: https://github.com/hulryung/markdown-prism I originally built this for myself. I wanted a lightweight Markdown viewer on macOS that: wasn’t Electron-based rendered GFM properly supported LaTeX math and Mermaid diagrams worked fully offline Most native apps I tried were either minimal but missing key features (math, diagrams), or full-featured but Electron apps. I wanted something in between — native feel, but with the mature JS Markdown…
What it does
In the maker’s words, at launch
Hi HN, I built a macOS-native Markdown viewer/editor called Markdown Prism. Website: https://prism.huconn.xyz GitHub: https://github.com/hulryung/markdown-prism I originally built this for myself. I wanted a lightweight Markdown viewer on macOS that: wasn’t Electron-based rendered GFM properly supported LaTeX math and Mermaid diagrams worked fully offline Most native apps I tried were either minimal but missing key features (math, diagrams), or full-featured but Electron apps. I wanted something in between — native feel, but with the mature JS Markdown ecosystem. How it works It’s a hybrid approach: SwiftUI for the native app shell WKWebView for rendering markdown-it, KaTeX, highlight.js, and Mermaid.js bundled locally So you get native performance and integration (Quick Look, file watching, drag-and-drop), but still benefit from battle-tested JS rendering libraries. Everything is bundled for offline use. Features Split-pane editor with live preview (400ms debounce) GFM (tables, task lists, strikethrough) LaTeX math via KaTeX Mermaid diagram support Syntax highlighting (190+ languages) Quick Look extension (preview .md in Finder) Dark mode File watching for external edits Install via: brew install hulryung/tap/markdown-prism or download the DMG from the website. It’s free and open source (MIT), macOS 14+. Would love feedback — especially from people who use Markdown heavily. What’s missing? What would make this your daily Markdown tool?

I'm not the author of the app (nor i have any connection with them, just a random user). iA Writer and Writer Pro aren't well suited for me as a developer. They feel quite "strange" to me. Mou is a good option (free too) but still missing some features. So far this, this editor is the most complete user-friendly. Hope it helps!
