Worth knowing
OpenTodoList
- There is no hosted sync service: using a library on several devices needs a Nextcloud, ownCloud, WebDAV or Dropbox account, or an outside sync tool.
- No web version is listed; it runs as an installed app on Android, iOS, Linux, macOS and Windows.
- The AI integration currently covers recipe import only, and an online provider needs the user's own API key, which may carry separate costs.
Vikunja
- Vikunja Cloud has no free plan. The free option is self-hosting, where server maintenance, updates and backups are your job.
- The mobile app is an alpha pre-release for Android that the docs say covers only very basic features, and the maker gives no iPhone support.
- The admin panel, audit logs and time tracking belong to Vikunja Pro, a paid add-on for self-hosted instances in private beta with no public prices.
- Cloud prices are listed in euros only, and the vendor describes its CalDAV integration as early alpha with known bugs.
Key features
OpenTodoList
- Libraries
- A library is a container for todo lists, notes, images and recipes, so related items stay together. Each library can be given its own color.
- Todo lists, todos and tasks
- A todo list holds todos, and each todo can be broken into tasks. Items can have due dates and recurrence, and a schedule view shows what is due across all libraries.
- Notes with pages
- A note is a text container that can take additional pages, which turns it into a small notebook. Images are separate items with a title and description.
- File-based storage
- Each library is a normal directory of files on disk, so it can be backed up, inspected, or synced with an outside tool the user already trusts.
- Sync through your own storage
- Libraries sync through Nextcloud, ownCloud, generic WebDAV servers or Dropbox. Sync is chosen per library, and a local library is never copied to a server.
- Recipes with optional AI import
- Recipes hold ingredients, steps, notes and yield. An optional AI action turns pasted text or a web page into a recipe, using Apple's on-device model or an OpenAI-compatible provider.
Vikunja
- List, kanban, Gantt and table views
- Each project can be shown as a list, a kanban board, a table with selectable columns or a Gantt chart, and you can switch between them at any time.
- Quick Add Magic
- Typing a date, a *label, an @assignee, a +project or a !priority into a task title sets those fields as the task is created. It works in the web UI.
- Sharing, teams and link shares
- A project can be shared with one user, a team or a link. Link shares let people view or edit tasks without an account, with the same permission levels.
- Reminders, repeats and relations
- Tasks take due dates, reminders, repeat intervals, priorities, labels, attachments and subtasks, and can be related to tasks in other projects, for example as blockers.
- Imports and CalDAV
- Built-in importers cover Todoist, Trello, Microsoft To Do, TickTick, WeKan, Planka and CSV files. A CalDAV integration syncs tasks with outside clients such as iOS Reminders.
- API, webhooks and MCP
- A documented REST API with token authentication, webhooks, a vendor-maintained community node for n8n and, from version 2.7.0, an MCP endpoint for AI assistants.
