Logseq vs SiYuan
Personal knowledge management system with WYSIWYG block editing, bidirectional links, spaced repetition flashcards, a relational database, and end-to-end encrypted sync. Here is how SiYuan ($0/mo open source) stacks up against Logseq ($10/mo) across cost, hosting, data privacy, and real-world trade-offs.
SiYuan is a verified AGPL-3.0-licensed open-source replacement for Logseq. Switching from Logseq ($10/mo) saves $120/yr per solo seat, or $600/yr for a 5-person team. Deployment: Runs on Self-host.
The catch: SiYuan is a powerful local block database but lacks Anytype's encrypted peer-to-peer spaces, object-type UX, and relationship-centric collections.
