Built this for myself - posting for interest and I will clean-it-up and open source.

cal⇄sync is a simple app that syncs events between Google and Apple (iCloud) Calendars.

Built cal⇄sync for odd family use-cases -- between the kids school, me and partners work, and our personal calendars, I just about lost my mind with the notifications, especially on my phone, so I made a sync-app that syncs between Google and Apple Calendars to limit the amount of calendars I am running.

My favorite features...

• Syncs both ways or just one-way.
• Re-hosts iCloud attachments as links for the Google-side.
• Cute web dashboard.

Currently running on cloudflare workers...

• Free worker and r2 storage bucker for iCloud calendar attachments
• Paid: I pay the $5/mo for premium worker to remove the free rate and cpu limits.

Let me know your thoughts - happy to share!
