Show HN: Marky – 에이전트 코딩을 위한 경량 Markdown 뷰어

A fast, native markdown viewer for macOS. Open any .md file from the terminal and get beautiful rendering of tables, code blocks, task lists, math, and diagrams — with live reload when the file changes on disk. Built with Tauri v2, React, and a markdown-it rendering pipeline. - CLI-first — marky README.md opens a window.marky ./docs/ opens a folder. - Live reload — edits on disk (from your editor, Claude, etc.) update the view instantly. - Folders — add folders as persistent workspaces (Obsidian-style). They appear in a sidebar and restore on launch. - Cmd+K command palette — fuzzy-search files across all open folders, powered by nucleo. - Syntax highlighting — Shiki with VS Code themes for accurate, beautiful code blocks. - Math — KaTeX rendering for $inline$ and$$display$$ math. - Mermaid diagrams — fenced mermaid blocks render as SVG. - GFM — tables, task lists, strikethrough, autolinks, footnotes. - Light & dark themes — follows system preference or toggle manually. - Sanitized rendering — all HTML is run through DOMPurify. Safe to view untrusted markdown. - Small & fast — native webview, no Electron. Production .dmg is under 15 MB. NOTE: I am currently waiting for apple developer review so for the time being the app is not signed. This will be fixed soon brew tap GRVYDEV/tap brew install --cask GRVYDEV/tap/marky # This is temporary until I can sign the binary xattr -cr /Applications/Marky.app Requires Rust, Node.js, and pnpm. git clone https://github.com/GRVYDEV/marky.git cd marky pnpm install pnpm tauri build ./scripts/install-cli.sh The install script symlinks marky to ~/.local/bin/ .
