[Updated] The demise of CopperheadOS and rise of its successors

New updates are being added at the bottom of this story…….

Original story (published on February 5, 2019) follows:

Remember CopperheadOS? The privacy centric, Google-less version of Android with enforced security hardening was created by a two-man team based on Toronto. Their startup, Copperhead Limited, used to sell Nexus and Pixel phones with preinstalled CopperheadOS.

Unfortunately it did not last long. The differences in business policy led to a fight between the CEO James Donaldson and the lead developer Daniel Micay. James ultimately fired Daniel.

Daniel is very much vocal on the social medias. He continues to communicate with his followers over Twitter and reddit after cutting the cord from CopperheadOS.

His patches to AOSP get merged by Google frequently. Mocking the shortcomings of the claims by Copperhead Limited is a favorite game for him.

Without the presence of Daniel, Copperhead has failed to continue providing monthly updates. Their long term support phones are 1st and 2nd gen Google Pixels, which are officially upgraded to Android 9 Pie by Google. Copperhead still treats them with Android Oreo along with Daniel’s old codebase.

What happened next

Well, we all know the drill.

RattlesnakeOS

Open source enthusiasts have tried to come up with alternatives of CopperheadOS. One such example is RattlesnakeOS. The developer doesn’t want to blatantly replicate the former, but tries to bring some of its core facilities on top of AOSP.

RattlesnakeOS was created initially as an alternative to CopperheadOS, a security hardened Android OS created by Daniel Micay, after it stopped being properly maintained back in June 2018. To be clear, this project is not attempting to add or recreate any of the security hardening features that were present in CopperheadOS. Instead, it is looking to fill a gap now that CopperheadOS is no longer available in its previous form, as there are no real alternatives that provide the same level of privacy and security.

Dan Vittegleo AKA dan-v is the man behind the ambitious project, who also came up with ‘rattlesnakeos-stack’. It is a nifty cross-platform tool to anchor the whole build process via AWS cloud infrastructure with user-supplied signing keys.

To compare with other custom ROMs, RattlesnakeOS enforces critical security features like enabled verified boot and completely replaces core Google services with third party open source alternatives. Ready-to-flash precompiled builds are not possible in this case, as they are signed by user specific keys.

Android Hardening / Hardened Android Open Source Project

This should not be considered as a fork, as this one is created and maintained by the principal developer of CopperheadOS himself.

Yes, Daniel brought the essence of CopperheadOS back under a new name. For now, the developer doesn’t want to call them production ready. The famous port of OpenBSD’s malloc implementation is the main attraction.

Kernels older than 4.4 are not supported so OG Pixels are dropped from the supported device list. Builds for 2nd and 3rd gen Pixel phones are available via seamlessupdate.app.

#!os

Another example is #!os / hashbangOS, which clearly draws its inspiration from CopperheadOS.

Heavily inspired by the former CopperheadOS (RIP) project. We seek to provide a trustable path to free public AOSP builds patched for privacy and security.

Unlike RattlesnakeOS, they are planning to provide reproducible builds using automated CI/CD. Rest of the features are pretty much same.

These guys follow Android Hardening as closely as possible and integrate patches from it. 2016 1st gen Pixels are also supported by this project.

Those who are still curious about the fundamental differences between these forks and other popular custom ROMs, hashbang guys have you covered.

Rocking a Pixel and want to taste a Google-less Android? Give them a try and let us know.

1:45 pm (IST): While our original article highlighted the potential closure for Copperhead, the company is still operating under James Donaldson and has even outlived the alternatives we mentioned above — RattlesnakeOS and hashbangOS.

The latest release of CopperheadOS is based on Android 13 and is available for the Pixel 6a and the Pixel 7. So if you’re looking out for a privacy-focused ROM, CopperheadOS is an easy recommendation.
