Musubi vs OpenFamily

Both stand on family calendar apps. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Musubi

Free plan AndroidiPhoneSelf-hosted+1

Musubi combines calendar connections, shared events, tasks, and mobile apps, and it is free during early access. Its server needs to read event data for sharing and sync, so the service is not end-to-end encrypted.
