Rune
Markdown that renders as you type — code, diagrams, math
What it does
Rune is a focused, fast Markdown editor for desktop. In one pane, your Markdown formats the moment you type — only the line you're on shows raw source. Code, Mermaid diagrams, KaTeX math, and tables render right where you write them, while the page stays calm. Local-first (plainmd files), built on Rust so it opens instantly and stays small. Korean/CJK is first-class. Free & open source (MIT) for macOS, Windows, and Linux.

- LJLobster.js – Extended Markdown with layout blocks and footnotesMar 2026 · github.com · ▲7
Hi HN! I built lobster.js which is an extended Markdown parser that renders directly in the browser — no build tool, no framework, no configuration. The entire setup is a single script tag: import { loadMarkdown } from "https://hacknock.github.io/lobsterjs/lobster.js"; loadMarkdown("./content.md", document.getElementById("content")); It's particularly useful for GitHub Pages sites where you want Markdown-driven content without pulling in Jekyll or Hugo. --- What makes it different from marked.js or markdown-it: Standard parsers convert Markdown to HTML — that's it.…
