Siyuan
Siyuan is a self-hosted knowledge management platform designed for private note-taking and information organization. It functions as a local-first application that stores all user content as plain text files on the local file system, ensuring data ownership and offline availability.
The platform utilizes a block-based document model, which structures information as a tree of independent content blocks to facilitate granular manipulation and bidirectional linking. Users can extend the core functionality through a sandboxed plugin architecture, allowing for the development of custom themes and scripts that modify the editor behavior and user interface to suit specific workflows.
The software is built as a containerized application, supporting deployment within isolated environments to standardize dependencies and simplify maintenance across various hosting infrastructures. It maintains consistency across multiple devices through a persistent socket connection that propagates state changes in real time, while the interface utilizes virtual document object model reconciliation to manage updates efficiently.
