GrapheneOS vs CalyxOS — Which One Should You Use?
Both GrapheneOS and CalyxOS are privacy-focused, but they target slightly different types of users. Here’s a quick comparison:
| Feature | GrapheneOS | CalyxOS |
|---|---|---|
| Primary focus | Maximum security, privacy & hardening | Privacy and usability with extra features |
| Target users | Security professionals, journalists, highly privacy-conscious users | Users switching from stock ROMs who want privacy + convenience |
| Google Play support | Optional sandboxed Play services (no system-level privileges) | MicroG & privacy tools, more convenient for some apps |
| Customization & UI | Very close to stock AOSP, minimal visual changes | More tweaks & features than stock, but still not a heavy custom ROM |
| Security hardening | More aggressive: memory tagging, stricter sandbox, exploit mitigations | Improved vs stock, but less aggressive than GrapheneOS |
| Best for | Maximum security & privacy, okay with strict, no-nonsense setup | Balanced privacy + comfort for daily use |
Short version: If you want the strictest security model and are fine with fewer extras, GrapheneOS is the better pick. If you want privacy but with more convenience and built-in tweaks, CalyxOS can be a good alternative.
