MindMapVault vs MindMup

MindMapVault is an encrypted vault for creating, editing, and storing mind maps, notes, attachments, and map relationships. For cloud use, map content is encrypted on the device with AES-256-GCM before upload, and the server stores ciphertext; its hybrid key encapsulation combines X25519 and ML-KEM-768. Cloud Free provides 25 MB encrypted storage, three active shares, five published maps, and a 5 MB maximum file size. Cloud Pro costs $50 a year and provides 1 GB, 100 active shares, effectively unlimited published maps, and a 50 MB maximum file size. A free desktop-local app and self-hosted Docker deployment are also listed. The desktop app works offline without an account or server and keeps data on the device. The web app can be installed as a PWA on iPhone and Android, with offline use supported. Imports include FreeMind, Freeplane, WiseMapping, XMind, and Markdown; exports include JSON, Markdown, FreeMind, PNG, and PDF. There is no real-time collaboration, and credentials cannot be recovered for existing encrypted vault contents if lost.
