Unofficial Flatpak builds that Flathub does not carry, published as one GPG-signed Flatpak remote:
https://francoism90.github.io/flatpaks/index.flatpakrepo
The two proprietary apps use an extra-data source: their .deb is downloaded from the vendor onto
your machine at install time, checksum-pinned in the manifest. No vendor binaries are hosted here.
This repo replaces the separate ai.claude.desktop, org.freedesktop.Sdk.Extension.podman and
com.visualstudio.code repos, which were built with Flatter.
