Tasks.org vs Vikunja

Tasks.org is a free, open-source task management app for Android, with desktop builds for Windows, macOS, and Linux. It organizes work with lists, tags, filters, manual sorting, and subtasks that can nest to unlimited depth. Tasks can recur, trigger notifications, and use location-based reminders. The free plan includes unlimited tasks, lists, tags, and reminders, and requires neither an account nor an internet connection. Mobile offline use is supported; synchronization options include Google Tasks, Microsoft To Do, DAVx⁵, CalDAV, EteSync, and DecSync CC. Tasks.org Cloud uses CalDAV and can connect with apps including Outlook, Thunderbird, and Apple Reminders. Its Cloud plan adds cross-device sync, list sharing with up to five guests, and email-to-task. The desktop download page offers Windows, macOS, and Linux builds, though the homepage labels desktop as alpha. Name-your-price starts at $0.99 per year, while Tasks.org Cloud costs $2.49 per month, billed annually at $29.99 per year. Calendar sync is not supported.

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.
