Lunatask vs Vikunja

Lunatask is an encrypted, cloud-based personal organization app for Windows, macOS, Linux, iOS, and Android, with API and browser-extension support. It combines to-do lists, habit tracking, journaling, life tracking, notes, and relationship reminders. Task workflows include a Kanban-like approach, Must/Should/Want, the Eisenhower Matrix, timers, and work-in-progress limits. It also tracks moods, emotions, energy, and stress. Notes and notebooks can be PIN-protected, and calendar connections include Google, Outlook, iCloud, Proton, Fastmail, Hey, Facebook Events, iCal/ics, and CalDAV; these currently sync one way into Lunatask. Free includes 2 Areas of Life, 7 Daily Habits, and 30 Relationships. Premium costs $6 a month when billed annually or 8.00 USD monthly, adding unlimited areas, habits, and relationships plus calendar integrations and additional planning tools. Data is encrypted on the device before cloud storage, although task metadata remains unencrypted. Offline use is temporary, with later synchronization.

Vikunja is an open-source task and project management app that can be self-hosted or used through cloud plans. Tasks can be organized as lists, Kanban boards, Gantt charts, or tables, with due dates, reminders, repeating schedules, subtasks, labels, priorities, assignments, attachments, and relations. Projects can be shared with another user or team, or through a link that does not require an account. Vikunja includes CalDAV integration and migration support for Todoist, Trello, and Microsoft To-Do. The self-hosted core is free under the AGPLv3 license, but server maintenance, updates, and backups are self-managed. Paid cloud plans start with Personal at €4 a month, including 10GB of attachment storage. Family costs €10 a month for up to five users, while Organization costs €5 a month per user. Vikunja Cloud is hosted at Hetzner locations in Germany and Finland. Desktop apps are available for Linux and Windows; the maker notes that mobile apps support only very basic features.
