カスタムAndroid ROM

A fully de-Googled ROM built on LineageOS, developed by the nonprofit /e/ Foundation, aimed at mainstream users who want a genuinely Google-free phone without needing to be a power user to set it up.

A newer, minimalist-focused LineageOS-based ROM prioritizing speed, stability, and a clean interface over heavy feature additions — one of the more actively growing projects in the custom-ROM space since its 2024 launch.

A privacy-focused ROM from the nonprofit Calyx Institute, positioned between GrapheneOS's security-first approach and mainstream custom ROMs — includes an optional de-Googled microG layer and a bundled VPN (Guardian Project's own).

A LineageOS-based ROM aiming to replicate the stock Google Pixel software experience closely, with Pixel-style features added on top, rather than crDroid or Paranoid Android's heavier customization focus.

The most security-hardened custom Android ROM available, built specifically around Google Pixel hardware to take advantage of its security chip and verified boot — used by security researchers and high-risk users specifically for its hardening work, not just its privacy features.

The largest and longest-running custom Android ROM project — a direct continuation of CyanogenMod, and the base that most other custom ROMs on this list are themselves built on top of.

One of the oldest custom ROM projects still actively developed, known historically for pioneering features (like PIE, its circular gesture-navigation control) that later influenced stock Android itself.

A newer AOSP-based ROM built to replicate the Google Pixel experience with Google apps included by default, positioned as a spiritual successor to the discontinued PixelExperience ROM.

A LineageOS-based ROM focused on performance and deep customization, with an unusually fast update cadence and one of the largest actively-maintained device lists outside LineageOS itself.
