Deploy SiYuan in one click installation.
Privacy-first personal knowledge management system with block-level editing, two-way linking, and spaced repetition.
What you can build with SiYuan
SiYuan is a privacy-first, self-hosted personal knowledge management system with over 41,000 GitHub stars. It combines a block-level WYSIWYG Markdown editor with two-way linking, SQL query embedding, and a flashcard spaced repetition system — making it a compelling alternative to Notion, Obsidian, and Roam Research for users who demand full data ownership.
Self-hosting SiYuan on your VPS means your notes, documents, and knowledge graphs never leave your own server. With AI writing assistance via OpenAI, PDF annotation, web clipping, and a community plugin marketplace, SiYuan delivers a modern, feature-rich experience with zero cloud dependency.
Key features of SiYuan
Block-Level Editing
Every paragraph, heading, and list item is a referenceable block, enabling fine-grained linking and precise knowledge graph construction.
Two-Way Linking
Bidirectional references and backlinks connect ideas across documents, helping you surface relationships as your knowledge base grows.
Spaced Repetition
Built-in flashcard system applies spaced repetition algorithms to any block, turning your notes into an active learning tool.
SQL Query Embedding
Embed live SQL queries inside documents to dynamically aggregate and display data from across your entire knowledge base.
Plugin Marketplace
Community-built plugins and themes extend SiYuan with additional workflows, integrations, and visual customizations without modifying core files.

Docker VPS hosting you can rely on
I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
