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 and runs in Docker, offering a web UI with live preview and eliminating the need for proprietary clients or paid sync services.

Problem

Users of Obsidian/Notion need to install the app on each device and manage syncing, which can be cumbersome and costly.

Outcome

Users can self‑host a free, open‑source note‑taking application that stores notes as plain markdown, eliminating the need for proprietary clients and paid sync services.

Workflow

• Install Docker on the host machine
• Clone the NoteDiscovery repository from GitHub
• Run the Docker container with the provided configuration
• Open the web UI in a browser
• Create, edit, and preview markdown notes directly in the browser

Evidence

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