nodum
Notes that link back.
Nodum is an open-source knowledge base for the web — markdown notes, wikilinks, backlinks, and an interactive knowledge graph. Like Obsidian, but in your browser.
Linked thinking
Write in markdown, connect ideas with [[wikilinks]], and watch backlinks surface connections you forgot you made.
A living graph
Your vault as an interactive, GPU-rendered force graph — smooth at tens of thousands of notes.
Your notes, forever
Plain markdown in, plain markdown out. Import an Obsidian vault, export a zip anytime. Fully open source.
