Logseq
Logseq is completely free to use. You can download it and access all features without paying anything. The app is open-source, meaning the code is public and anyone can review it or contribute to its development.
For users who want to sync their notes across multiple devices, Logseq offers a beta sync service through their Open Collective support program. By becoming a monthly supporter with a $5 or $15 donation, you get early access to Logseq Sync, which keeps your notes updated in real-time across all your devices.
The sync service is still in beta testing, so the team is working to make it more stable. Once it launches to everyone, a regular subscription system will be available. Supporting Logseq also helps fund development and keeps the project growing with new features.
SiYuan
SiYuan offers three pricing options designed to meet different user needs. The Free version gives you lifetime access to all core features for local use, including block editing, markdown support, and offline access. This makes SiYuan perfect for individual users who want complete control without any cost.
The PRO Features package costs $64 as a one-time lifetime payment (discounted from $96) and unlocks integration with third-party services like Amazon S3 and WebDAV for sync and backup.
The Subscription plan costs $148 lifetime (discounted from $296) and includes everything in PRO plus official cloud sync with 8GB storage space, cloud inbox for collecting ideas, and automatic backup. Limited seats are available for this plan.
All features for creating and managing notes locally remain free forever, even for commercial use.
