FYI I've made a patchset that pretty much allows me to actually use the EAS --local builds offline and without an EAS account, so it's in fact possible, even though they, for obvious reasons (e.g. https://github.com/expo/eas-cli/issues/1606), don't encourage it.
Would you mind sharing this? I’ve only used expo for experimental non-production apps so far but it works be great to be able to do this if ever needed. Reading this thread makes me a bit more hesitant about using expo.
My full build process is somewhat more complicated to keep my $HOME clean and remove other impurities, but just these patches should be enough to enable offline building.
EAS CLI is designed for EAS, the hosted services. It is intended to use your EAS account, which I suspect is why the PR wasn't accepted.
Expo CLI is for entirely local builds. Run "npx expo prebuild:{android,ios}" to generate your Android Studio and Xcode projects, and build them with the IDEs or their respective CLI tools directly.
