24 alternatives to JavaScript-first, open-source WYSIWYG DOCX editor
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.
A JavaScript-based, open-source WYSIWYG editor for DOCX files created with Claude Code assistance. Built to address the lack of solid open-source alternatives in the market, it offers functional core text editing… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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…

We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0. A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation. The core rendering engine is framework agnostic, with React and Vue ui adapters on top. It’s Apache 2.0. Happy to answer questions.

Hi all! TikZ is a widely-used LaTeX package for drawing figures in papers. It uses commands like \draw[->] (0,0) -- (1,2); to draw lines, shapes, text, etc. Academics usually code up their figures by hand, so there is lots of twiddling around with the coordinates and recompiling until things look nice. I guess it’s a bit like SVG, but it’s more code than markup, for example it has loops with \foreach. I built an open-source WYSIWYG TikZ editor (available for web and desktop) that allows you to edit your TikZ source code visually by dragging and resizing elements. It simultaneously shows the…

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…

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…

I built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding. What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback. Offline support – Works without internet. You can even install it as a PWA and use it like a native app. No Login Required – Just visit, code, and preview. Login only if you want to save/share. Savable & Shareable Links – Save scripts in the cloud and get shareable links. Customizable Editor – Themes, fonts, auto-format on save, layout tweaks, line…

Word in web is a pure JS docx editor/renderer benched against MS Word directly. This was largely inspired by Eigenpal going closed source, and some personal frustrations I had with working on complex Word templates, pleading papers, etc... and not having a clean way to view/edit them without owning MS Word (which I did just eventually buy but it sucked). This was also an exercise in highlighting the value of good evals for Agents to bench against. Instead of just throwing the OOXML standard at an agent and letting it spin, I put together a large corpus of Microsoft Word docs -…

(spoiler: its XSLT) I've been working on a little demo for how to avoid copy-pasting header/footer boilerplate on a simple static webpage. My goal is to approximate the experience of Jekyll/Hugo but eliminate the need for a build step before publishing. This demo shows how to get basic templating features with XSL so you could write a blog post which looks like My Article some content hello hello Some properties which set this approach apart from other methods: - no build step (no need to setup Jekyll on the client or configure Github/Gitlab actions) - works on any webserver…
