Amazing Marvin vs Vikunja

Amazing Marvin is a personal productivity app for organizing tasks and planning work. It supports recurring tasks, time estimates, color coding, focus sessions, time blocking, workload planning, and review reports. Users can choose Day Planning, List-Based, Spontaneous, or GTD workflows, and adjust more than 300 settings, layouts, themes, colors, and feature controls. Calendar sync is available, and imports are supported from Todoist, TickTick, Asana, ClickUp, and Google Calendar. The app runs on the web, Windows, macOS, Linux, iOS, and Android. Marvin Pro starts at $8 per month; annual billing costs $96 per year and saves 33%. The 14-day trial provides full access without a credit card, but after the trial users cannot add or complete tasks until subscribing. Support includes personal email contact, and community channels include Facebook Group, Discord, and Reddit. Users can cancel through settings at any time.

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.
