iCloudBridge: Open‑source macOS tool to sync iCloud with Nextcloud, Bitwarden and more

A new open‑source macOS project called iCloudBridge aims to let users mirror and sync content from Apple iCloud to third‑party services. The app reportedly supports Notes, Reminders, Photos and Passwords, targeting users who want to integrate iCloud data with platforms like Nextcloud or self‑hosted password managers such as Bitwarden and Vaultwarden.

iCloudBridge is designed for users who prefer self‑hosting or need cross‑platform access to their Apple data. Instead of manual exports, the tool can automate syncs so content remains available on both Apple devices and alternative services.

Supported data types (reported)

• Notes & Reminders: Sync textual notes and task lists to compatible services.
• Photos: Mirror or copy photo libraries to other cloud stores.
• Passwords: Export or sync Keychain entries into Bitwarden/Vaultwarden (handle carefully).

Who should consider iCloudBridge

This project is mainly for privacy‑minded users, Nextcloud adopters and anyone running self‑hosted password managers who wants easier access to their iCloud content outside Apple’s ecosystem. It can also help users migrate data or keep backups on platforms they control.

Security & privacy considerations

Syncing sensitive items—particularly passwords and private photos—requires caution. Because iCloudBridge is open source, its code can be inspected, but users should verify how credentials are handled, whether transfers are encrypted, and how the destination services protect stored data. Test with non‑sensitive data first and review documentation.

Setup notes & requirements

• iCloud access and appropriate macOS permissions are likely required to read Notes, Reminders, Photos and Keychain items.
• Configuration will include pointing the app to target services (Nextcloud URL, Bitwarden/Vaultwarden server details).
• Expect manual setup steps and checks for encryption/keys when syncing passwords.

Discussion: Would you use iCloudBridge to mirror your iCloud content to Nextcloud or a self‑hosted password manager, or do privacy concerns keep you on iCloud? What safeguards would you want before syncing passwords?
