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

Description and use

NoteDiscovery is a free, self-hosted note-taking app that stores everything as plain markdown files, deploys via Docker, and provides a modern web UI with live preview. The project is in early stages and does not yet match Obsidian's full capabilities.

Problem

The user wants a self-hosted note-taking alternative to Obsidian that is free, stores notes as plain markdown files, and works across multiple computers without syncing hassle.

Outcome

NoteDiscovery provides a free, self-hosted, MIT-licensed alternative to Obsidian that stores notes as plain markdown files, deploys via Docker, and offers a modern web UI with live preview.

Workflow

• Build NoteDiscovery as a self-hosted note-taking app
• Store everything as plain markdown files
• Deploy via Docker
• Provide modern web UI with live preview

Evidence

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

Why I made this: I do like Obsidian and been using it for quite some time, but having to install in all different computers to use it in, plus the hassle of syncing notes made me think about a new alternative.

Key features: - Docker - Plain markdown files - Modern web UI with live preview

It's 100% free and MIT licensed.
