Self-hosted personal knowledge workspace with block-level notes, bidirectional links and AI agents.
In validation
Automatic installation for this solution is ready and currently going through our tests on a real server. Ordering will open as soon as validation is complete.
SiYuan is an open-source (AGPL-3.0) personal knowledge management system built in Go with SQLite. Unlike cloud-based tools such as Notion or Roam Research, all your notes, attachments and history stay on your own VPS — encrypted at rest, accessible from any device via the web UI or the official desktop and mobile apps.
Every paragraph is a block — you can reference, embed and query any block from anywhere in your workspace. Bidirectional links and the built-in graph view give you a searchable map of how your ideas connect, without locking you into a folder hierarchy.
On a ServOrbit VPS, SiYuan runs in a single Docker container using fewer than 256 MB of RAM and exposes its interface on port 6806 — protected by a generated access code and proxied by nginx over HTTPS once you attach a domain.
Keep your project notes, meeting logs and personal wiki on your own VPS. SiYuan's block editor and databases cover the same ground as Notion pages — without the subscription or the data sharing.
Link code snippets, architecture decisions and reading notes with bidirectional links. The graph view surfaces hidden connections between topics; the SQL query language lets you pull every note tagged #architecture into a dashboard.
Use the daily journal for quick captures, embed referenced blocks in long-form drafts, and export finished pieces to Markdown or Word. The AI integration can summarise your notes or draft from a block outline.
Guide optimized for ServOrbit Cloud VPS.
SiYuan does not require a domain name. Open an SSH tunnel from your local machine: ssh -L 6806:127.0.0.1:{{ expose_port }} root@<your-vps-ip> then open http://localhost:6806 in your browser. For permanent access from desktop or mobile apps, attach a domain from your ServOrbit dashboard — nginx proxies to the container over HTTPS — or use the free {app}.{dns_slug}.servorbit-dns.com subdomain included with every VPS.
SiYuan is protected by a generated access code displayed in your ServOrbit credential vault. Enter it on the login screen. You can change it later from Settings → Account → Access auth code.
Click the + icon in the left panel to create a notebook. Inside a notebook you can create documents, daily notes or templates. Start typing to create block content — headings, paragraphs, lists, code blocks and tables are all separate, linkable blocks.
Type [[ to insert a block reference to any note in your workspace. Open the graph panel from the left sidebar to visualise all bidirectional links. As your workspace grows, the graph becomes a navigable map of your knowledge.
ssh -L 6806:127.0.0.1:<port> root@<vps-ip> then http://localhost:6806. For permanent HTTPS access from the desktop or mobile apps, attach a domain from your ServOrbit dashboard or use the free {app}.{dns_slug}.servorbit-dns.com subdomain.Lightweight open-source note-taking app: capture ideas, run a personal journal or share notes with your team — self-hosted on your VPS.
