Musubi information
What is Musubi?
Musubi is a shared calendar built for partners, families, friends and other small groups. It brings Google Calendar, Apple iCloud, Outlook and Microsoft 365, and CalDAV calendars into one view with two-way sync.
Shared calendars are private and invite-based, with owner, editor and viewer roles. You can keep separate calendars for different groups while seeing everything together in one place.
Events are not limited to a single calendar. The same event can be linked to multiple calendars, so it can appear everywhere it is relevant without creating separate copies.
Musubi includes day, week, month and agenda views, recurring events, reminders, realtime updates, Android home screen widgets, availability polls and public event pages with RSVP support.
The app, server and sync engine are open source under the MIT License. Musubi can be used through the hosted service or run on your own server with Docker.
Musubi is currently in open beta.
