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…

This is a project I've been working on since the start of Covid-19. I built an app so that I don't have to put data into online tools like JWT debugger, JSON formatter, URL decoder, etc... https://devutils.app The app works entirely offline and is open-source. I'm selling the pre-built version of the app to earn some revenue for my time. If you want to try the app but can't afford the price or don't have XCode to build the app, drop me an email (my profile), I'll be happy to provide you a free build. I would love to hear all the feedback/suggestions. Thanks!

Flowershow▲174I'm Rufus, one of the founders of Flowershow. We love markdown and use it everywhere from making websites, to docs, to knowledgebases. Plus AI splits it everywhere now. Got tired of the framework/config/deploy overhead every time we wanted to share a file or put a site online. So we built the thing we wanted. Files in. Website out. "Vercel for Content" is our aspiration - make deploying (markdown) content as fast, seamless and easy as Vercel did for JS. Command line plus you can connect to github repos, use Obsidian via plugin, or drag and drop files. npm i -g…

(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…

As a teacher, we keep our slides as markdown files in git repos and want to build these automatically so they can be viewed online (or offline if needed). To achieve this, I have created MkSlides. This tool converts all markdown in a folder to slides generated with Reveal.js. The workflow is very similar to MkDocs. Install: `pip install mkslides` Building slides: `mkslides build` Live preview during editing: `mkslides serve` Comparison with other tools like marp, slidev, ...: - This tool is a single command and easy to integrate in CI/CD pipelines. - It only needs Python. - The workflow…

Hi! I just made an obsdian alternative in terminal after searching for an Obsidian like TUI and got nothing. The closest I found was Glow, but it's only a markdown reader. I wanted something more powerful for the terminal, so I built one myself.

Hi HN, I’m sharing mochi.js (https://github.com/0xchasercat/mochi), a Bun-native, raw-CDP browser automation framework. It's designed to make programmatic browser use more effective by focusing on consistency and measured parity with regular traffic, purely from the JS layer, against stock Chromium. The most common forms of browser automation focus heavily on client-side line by line probes, which are mostly cosmetic. This makes people feel better but it doesn't have much relevance to actual WAF or anti-automation defences. Mochi.js focuses on what actually matters,…
