Atomic Blend vs Apple iCloud
Apple-grade privacy posture — without being locked to Apple devices.
Apple’s iCloud Mail, Calendar, and Notes are polished and privacy-conscious, especially with Advanced Data Protection enabled. The catch is the ecosystem: they work best — and sometimes only — on Apple hardware.
Atomic Blend gives you an encrypted suite that behaves identically on every platform, is fully open source, and can be self-hosted. You are not tied to one company’s devices or account.
| Atomic Blend | Apple | |
|---|---|---|
| End-to-end encrypted | Yes | Partial |
| Open sourceProton open-sources its apps, not its backend. | Yes | No |
| Self-hostable | Yes | No |
| All-in-one (mail · calendar · tasks · notes) | Yes | Yes |
| No per-seat pricing | Yes | No |
| Export & own your data | Yes | Partial |
Why people switch from Apple iCloud
Truly cross-platform
Use the same encrypted apps on any OS — not just iPhone and Mac.
Open source & auditable
Apple’s stack is closed. Atomic Blend’s code is public under AGPLv3.
Self-host and own it
Run the suite on your own infrastructure instead of inside iCloud.
Where Apple iCloud is still the better choice
We would rather you picked the right tool than the one we sell.
- Deep, seamless integration across Apple devices.
- Strong default privacy, especially with Advanced Data Protection.
- Free tier bundled with every Apple account.
