An open-source, collaborative, WYSIWYG Markdown editor▲460
Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

Mmdr – 1000x faster Mermaid rendering in pure Rust (no browser)▲47
I was building a Rust-based agentic coding TUI and needed to render Mermaid diagrams. Noticed the official mermaid-cli spawns a full browser instance (Puppeteer/Chrome) just to render diagrams. Decided to fix this. mmdr is a native Rust renderer. No browser, no Node.js. mermaid-cli: ~3000ms per diagram mmdr: ~3ms per diagram Supports 13 diagram types: flowchart, sequence, class, state, ER, pie, gantt, timeline, journey, mindmap, git graph, XY chart, and quadrant.

Line9 – A Mermaid rendering engine with its own layout▲87
Line9 is a new rendering engine for Mermaid flowchart diagrams that aims to remove the need for manual adjustment of layout. Mermaid is a popular text-based language for describing multiple types of diagrams. Several Mermaid rendering engines already exist. Most, like the original mermaid.js, use Dagre or ELK graph drawing libraries to automatically lay out their diagrams. I’ve used Mermaid for the past four years but often recreated my flowcharts in a diagram editor so that I could modify the layout to something that better suited my needs. Use Line9 when you want an automatic flowchart…

Direct manipulation flowchart editor without the mouse▲54
Hey HN, I made this because I wanted a fast editing experience when making flowcharts. Other tools (bottom)require clicking and dragging (or editing code). Knotend is keyboard centric and is supposed to feel more like editing a doc than dragging around boxes and arrows. I've tested in on safari and chrome desktop. Its difficult to use on mobile but you can view existing charts. I'd appreciate your feedback on how you use it, the design, any bugs etc. Thank you. Prior art - https://mermaid-js.github.io/ - Confluence (Atlassian) - draw.io - excalidraw EDIT: fixed the bug on…
