Memex is a Claude Code alternative built on Rust+Tauri for vibe coding2025 · memex.tech · ▲86Hi HN, TL;DR Memex is a cross-platform desktop app for vibe coding. Think ChatGPT + Claude Code rolled into one. Why we built it: We love chat tools like Perplexity and ChatGPT. We also love coding agents, like in Cursor and Windsurf. We don’t like that web-based app builders are opinionated about tech stack and we can’t run them locally. So, we built Memex to be a chat tool + coding agent that supports any tech stack. What it can do today: Claude Code-like coding. Agentic web search / research. Pre-built templates (e.g. fullstack, iOS, python + modal, etc). Inline data analysis + viz.…

OpenKnowledge – open source AI-first alternative to Obsidian/NotionJun 2026 · github.com · ▲381Hi 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…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time. Instead, I rejigged/relaunched it via a Reddit forum this February as free and open - and have now gathered a team of helpers to ensure that it keeps going each month even after I can’t…
