Self-hostable, web-based knowledge base with linked notes, backlinks, and a GPU-rendered graph.

Webfreeglobal

Nodum is a self-hostable, multi-tenant, web-based knowledge base with Obsidian-style linked Markdown notes, backlinks, a GPU-rendered knowledge graph, and real-time collaboration, canvas, and publishing. It targets teams who want a collaborative, self-hosted linked-notes knowledge base rather than a single-user desktop tool.
