About

What Cefrium is

Cefrium is a port of the Chromium Embedded Framework (CEF) to native Android (aarch64-linux-android). It lets an Android app embed the full Chromium engine — the same engine on every device — instead of the system WebView, with off-screen rendering, the CEF C API, and multi-process operation through Android services. It is distributed as a Gradle-integrated SDK.

Status

Cefrium is in early validation and not yet recommended for production use. It is published as open source for the community to evaluate, use, and extend; developers interested in co-maintaining are welcome — cefrium@proton.me.

Maintainer

Cefrium is developed and maintained by Juan Manuel Méndez Rey, Debian package maintainer, currently working with the Debian Chromium team on Chromium Embedded Framework packaging.

Maintainer OpenPGP key

The maintainer's OpenPGP fingerprint (a fingerprint is public; only the private key is secret) for verifying or signing the key:

Fetch it from keys.openpgp.org (gpg --keyserver hkps://keys.openpgp.org --recv-keys 2A840ED00DE669F4219B8B3302A79E3B82151695). At a key-signing event you can also exchange it with the Cefrium keysigning companion.

Development practices

Cefrium's architecture, design constraints, product direction, hardware testing, and maintenance are human-directed; implementation is significantly AI/LLM-assisted and validated against device behavior.
