  • Show HN: Files.md โ€“ open-source alternative to Obsidian
    What is this providing over similarly Markdown based open source note taking applications like Joplin? (https://joplinapp.org/) I've been a huge fan of the fact that my backend sync infrastructure is my own self-hosted S3 bucket with local clients handling the presentation layer. - Source: Hacker News / 3 months ago
  • An Introduction to Obsidian
    Shout out to Joplin (https://joplinapp.org/), which I use on a daily basis. It does most of what Obsidian does but has a free sync version where you just use your cloud drive as the storage. The main thing missing, from what I've found, is that it does do the "notes mind map". But I never really found that useful. - Source: Hacker News / 5 months ago
  • Ditching Obsidian and building my own
    I use Joplin (https://joplinapp.org) on mobile and pc(windows and Linux). Joplin has a free encrypted sync via OneDrive. - Source: Hacker News / over 1 year ago

  • Ask HN: What Are You Working On? (February 2025)
    Thanks! I built the editor using Tiptap (https://tiptap.dev/) does something similar. I'll think about this for sure, especially since I've been thinking of making it possible to save and read local files. If you'd like to try Gorby, send me an email and I'll be happy to give you a free license code :). - Source: Hacker News / over 1 year ago
