Vikunja
Open-source task manager (AGPLv3) with four views (list, Kanban, Gantt, table), project sharing and task assignment to a team. Self-hostable with Docker, native binaries or the install wizard; paid Vikunja Cloud offer with updates and backups, whose prices are on a page not read. Made and hosted in the European Union, no country stated. The page does not name French.
A task list with due dates, priorities, tags, Kanban views and sharing between people is the textbook case of simple custom work. Vikunja is precisely the finished example of this scope, open and self-hostable: try it before rebuilding. What remains: hosting, backups, updates and, if you want a mobile app or reminders, extra work.
What you lose
- The Gantt and table views, already finished.
- Reminders and notifications.
- Project sharing and rights.
- The cloud offer with updates and backups.
Existing alternatives to Vikunja
- Super ProductivityOpen source
Open-source task manager (MIT) with time tracking and daily planning, no account required.
What a home-built tool costs once it exists
- Hosting and database: a server cost, and automatic backups you actually test.
- Security and GDPR: dependency updates, an HTTPS certificate, protection of your customers’ data.
- Upkeep time: who fixes the tool on a Saturday night in the middle of service if the server goes down?
The prompt to build it yourself
Build a small task manager for my team, replacing a to-do tool. Context: a team of 5 people in a hotel, opening, maintenance and event tasks. To do: - Projects (opening, maintenance, events) and tasks with description, due date, priority, tags and owner. - Recurring tasks (daily, weekly) that recreate themselves automatically. - A list view, a Kanban board view and a «my tasks this week» view. - A morning email reminder of the day's tasks and overdue tasks. - Comments and attachments. Out of scope: Gantt, native mobile app. Stack: web app (PWA), SQLite. README: how to run, backup.
