Show HN: NoteDiscovery – Free Self-Hosted Alternative to Notion/Obsidian

Description and use

NoteDiscovery is a free, self‑hosted note‑taking app that stores data as plain markdown files and offers a web UI with live preview, simplifying cross‑device sync.

Problem

Users of Obsidian and Notion need a self‑hosted, free note‑taking solution that stores data as plain markdown and syncs across devices without proprietary software.

Outcome

NoteDiscovery provides a free, self‑hosted alternative to Notion/Obsidian that stores notes as plain markdown and offers a live‑preview web UI, simplifying cross‑device access.

Workflow

• 1. Install Docker on the host machine.
• 2. Pull the NoteDiscovery image from GitHub.
• 3. Run the container exposing the desired port.
• 4. Access the web UI via a browser to create and edit markdown notes with live preview.

Evidence

I built NoteDiscovery - a self-hosted note-taking app that stores everything as plain markdown files, and most importantly, free! :-)

Please bear in mind it’s in VERY early stages so it doesn’t get even close to what the excellent Obsidian can do, but for the time being it’s more than enough to suit my personal needs
