A recent example is [*metasnap.debian.net*](https://metasnap.debian.net). It is a 'meta archive' of
[*snapshot.debian.org*](https://snapshot.debian.org) which is itself archive of all packages in Debian. But let
me explain it the other way round: with *reproduce.debian.net*, we try to reproduce the packages as they are distributed by the Debian archive. For that, we need the same build environment (compilers, libraries, build tools, etc) that was used by Debian back when the original package was compiled. Luckily, *snapshot.debian.org* has all those packages, but they are not easily accessible via *apt*, Debian's package manager. So, *metasnap* provides a mapping from a package name and version pair to the APT repo on *snapshot.debian.org* needed to download it from. It was created by `josch` some time ago, and is an awesome work. But when we tried to reproduce more and more packages on *reproduce.debian.net*, we found that some were missing packages from the build environment — even though they where visible on *snapshot.debian.org*. We found that *metasnap* excluded some archive areas because they where not expected to be needed. Reimporting all the data took more than two months and surfaced a couple more flaws.

Yes. Another one is [`udd.debian.org/reproducibility/hello`](https://udd.debian.org/reproducibility/hello), where you
can list all packages of a Debian maintainer. It also lists source reproducibility and has nice filters as well.
