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

Description and use

NoteDiscovery is a free, self‑hosted note‑taking app that stores notes as plain markdown files, runs in Docker, and offers a modern web UI with live preview.

Problem

Users of Obsidian face challenges installing the app on multiple devices and syncing notes across them.

Outcome

NoteDiscovery provides a free, MIT‑licensed, self‑hosted alternative to Notion/Obsidian that simplifies note management by using plain markdown files and a web UI.

Workflow

• 1. Deploy NoteDiscovery using Docker.
• 2. Store notes as plain markdown files on the host.
• 3. Access the modern web UI with live preview from any browser.

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
