Important: licenses vary
Outline uses the Business Source License 1.1, and Anytype uses the Any Source Available License 1.0, so both are source available rather than OSI open source. Joplin's apps are AGPL-3.0-or-later, but Joplin Server has a Personal Use License. AppFlowy, Logseq, Standard Notes, and Docmost are AGPL-3.0 (Docmost with enterprise features), Notesnook is GPL-3.0, and Docs is MIT.
Closest to Craft
AppFlowy is the closest as a self-hostable workspace combining notes, databases, and AI, with local models supported. Docs offers real-time collaborative documents, Outline and Docmost are team knowledge bases and wikis, and Joplin, Notesnook, Standard Notes, and OpenNotas are encrypted notes apps.
Encryption and sync
Notesnook, Standard Notes, Joplin, and OpenNotas offer end-to-end encryption, and Anytype syncs peer to peer. Joplin Cloud sync is a paid add-on, though Dropbox or OneDrive sync works without paying, and Anytype and Notesnook have paid tiers for larger needs.
Maintenance status
Most projects had commits within days of this update. OpenNotas's last commit was in August 2026 and Justnote's in February 2026, so they are smaller and slower.
