Nirvana vs Vikunja

Nirvana is a to-do list app inspired by Getting Things Done®, available on web, Windows, macOS, iOS, and Android. Users can schedule tasks to appear when they are ready to act, set due dates for to-dos and projects, and organize work with tags, contacts, and areas. Filters can narrow tasks by tag, area, contact, energy, time needed, and other criteria. Notes support checklists, and search covers words in both to-dos and notes. Email forwarding can turn a message into a to-do, while users can choose days to receive their Focus list by email. Tasks stay up to date across devices, and the app supports reminders, subtasks, and recurring to-dos. Calendar sync is not supported. The free plan includes up to five projects and two areas; Pro costs $3 a month, billed annually at $36/year, and includes unlimited projects and areas, recurring to-dos, and priority support. The MCP server is available on every account, though free users cannot update existing tasks through it.

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.
