From the sources

Open-source and non-profit under GPLv3, vault-compatible cross-platform markdown notes app. It's based on Rust + Tauri v2 and under heavy development. We're looking for Linux distribution maintainers. Not affiliated with or endorsed by Obsidian or Dynalist Inc.; "Obsidian" is their trademark. Tested 2026-10-03 on fresh Ubuntu 26.04 LTS and Fedora 44 with Rust 1.98.0 (build ~2.5 min on 4 cores, binary runs and renders on both).

    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…

    Open-source obsidian.md sync server2023 · ▲416

    https://github.com/acheong08/obsidian-sync Hello HN, I'm a recent high school graduate and can't afford $8 per month for the official sync service, so I tried my hand at replicating the server. It's still missing a few features, such as file recovery and history, but the basic sync is working. To the creators of Obsidian.md: I'm probably violating the TOS, and I'm sorry. I'll take down the repository if asked. It's not ready for production and is highly inefficient; Not competition, so I hope you'll be lenient.

    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 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…
