ZetaJS – client-side LibreOffice widget and automation in the browser

Libredesk is a 100% free and open-source customer support desk, the backend is written in Go and the frontend is in Vue JS with ShadnCN for UI components. Unlike many "open-core" alternatives that lock essential features behind enterprise plans, Libredesk is fully open-source and plans to always stay this way. It's in alpha (v0.1.0) right now, but there’s a working demo available. I built this because I wanted a truly open and self-hosted alternative to platforms like Chatwoot, Intercom, and Zendesk. Would love feedback, suggestions, and thoughts from the community. GitHub:…

Hi HN! Last year, we shared marimo [1], an open-source reactive notebook for Python with support for execution through WebAssembly [2]. We wanted to share something new: you can now run marimo and Jupyter notebooks directly from GitHub in a Wasm-powered, codespace-like environment. What makes this powerful is that we mount the GitHub repository's contents as a filesystem in the notebook, making it really easy to share notebooks with data. All you need to do is prepend 'marimo.app' to any Python notebook on GitHub. Some examples: - Jupyter Notebook:…

Hi everyone! For our graph database, Memgraph [1], we have just built a WASM-based JavaScript client adapter called jsmgclient. One of our engineers has described in depth the process that he has used to achieve this. [2] If you have used WASM can you take a look at our approach and tell us what you think about our approach? Do you see any things that we should have done differently? [1] https://memgraph.com/ [2] https://memgraph.com/blog/wasm-introducing-the-very-first-wa...

A user friendly, serverless JavaScript SaaS CMS

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.
