In their own words
Musubi
Musubi is a shared calendar that combines calendars, tasks, and people for everyday planning. Events can appear in multiple calendars, with one update reflected wherever they are shown. It connects with Google Calendar, Apple iCloud, Outlook, Microsoft 365, and compatible CalDAV services including Nextcloud, Fastmail, and Radicale. Synchronization works both ways where provider permissions allow, while read-only calendars remain read-only. Views cover day, week, month, and agenda formats, and personal pages control which calendars and items appear. Tasks sit beside events with status, priority, due dates, and web list or Kanban views. Android and iOS apps provide mobile access; Android adds agenda and month widgets, with reminders scheduled on the device. Musubi is open source under the MIT License and can be self-hosted with Docker Compose v2, a domain, and HTTPS. Hosted Musubi costs nothing during early access. The hosted app and primary database run in Germany.
