24 alternatives to An open-source, collaborative, WYSIWYG Markdown editor
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…

Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…

Hi HN! I got so frustrated with modern WYSIWYG editors that I started to play around with building my own. The problem I had was simple: I wanted a low-tech way to type styled text, but I didn't want to load a complex 500KB library, especially if I was going to initialize it dozens of times on the same page. Markdown in a plain was the best alternative to a full WYSIWYG, but its main drawback is how ugly it looks without any formatting. I can handle it, but my clients certainly can't. I went down the ContentEditable rabbit hole for a few years, but always came to realize others had solved it…

I'm excited to introduce my own developed Markdown editor to everyone. It's built on the Monaco editor and designed specifically for developers. This editor integrates various features such as document management, resource management, and MDX extensions. You can embed images, audio, video, and even use plugins like drawing tools, calendars, and cards to showcase your creativity. What's even more thrilling is that it allows users to customize PostgreSQL table structures, insert and display data in Markdown documents, and even collect form submissions. My original intention in design was to…

We needed a JS-first WYSIWYG DOCX editor and couldn't find a solid OSS option, most were either commercial or abandoned. As an experiment, we gave Claude Code the OOXML spec, a concrete editor architecture, and a Playwright-based test suite. The agent iterated in a (Ralph) loop over a few nights and produced a working editor from scratch. Core text editing works today. Tables and images are functional but still incomplete. MIT licensed.

My partner usually writes substack posts which I then mirror to our website’s blog section. To automate this, I made a simple tool to scrape the post and clean it so that I can drop it to our blog easily. This might be useful to others as well. Oh and ofcourse you can instruct GPT to make any final edits :D

Hi HN, I built Ephe, open-source markdown paper for daily todos and thoughts. No sign-up, no ads, no subscriptions, no AI. ## Why I made this We have plenty of Markdown editors. And too many overwhelming to-do apps. But few tools combine both in a way that’s lightweight and focused. I thought that all I need is a single page to organize today. So I built Ephe. It uses CodeMirror v6, React(v19, React Compiler) and Vite with rolldown. ## What makes it different “Ephe” comes from ephemeral. The main goal is to organize what you need to do today. It isn’t for teams. It’s a quiet space for your…
