Dendron
Hierarchical Knowledge Management for Developers
About Dendron
Dendron is an open-source, local-first, markdown-based knowledge management tool that runs as a VS Code extension. It uses flexible hierarchical note structures with schemas and templates to help users organize, find, and work with any amount of knowledge. Unlike flat-file note tools, Dendron treats notes like a structured knowledge tree with clear hierarchies and predictable paths. It supports multiple vaults, cross-vault linking, daily journals, scratch notes, and publishing notes as a static site via Next.js. Note: Dendron entered maintenance mode in early 2023 and is no longer actively developed.
Pros & Cons
