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.

Problem

Users of Obsidian and Notion need a self‑hosted, free note‑taking solution that syncs across devices without proprietary services.

Outcome

Users can host their own note‑taking service, keeping all data in plain markdown files, with a web UI that offers live preview, eliminating the need for proprietary cloud services.

Workflow

• Install Docker on the host machine
• Clone the NoteDiscovery repository from GitHub
• Run the Docker container to start the web UI
• Create and edit notes directly in the browser, which are saved as markdown files on the server
• Access the same notes from any device by navigating to the server’s URL

Evidence

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