Mobian is currently based on Debian 12 "Bookworm" and is going to stabilize on it, while also having a "testing branch" based on the next Debian testing, "Trixie". There's also a related project called Droidian, that makes Debian run on Android phones that are not supported by a mainline kernel.

Please note: Mobian also have an additional repository with custom packages, which is not and will not be indexed on repology.org (see github issue, so not every package available to you on Mobian can be listed here.
