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 modern web UI with live preview.

Problem

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

Outcome

Users can host their own note‑taking service for free, with all notes stored as plain markdown, eliminating reliance on proprietary cloud services.

Workflow

• 1. Clone the GitHub repository or pull the Docker image.
• 2. Run the Docker container with a mounted volume for data persistence.
• 3. Access the web UI via a browser to create, edit, and preview markdown notes in real time.
• 4. Store notes locally as plain markdown files for portability and version control.

Evidence

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