I'm very excited about this project, but it could really do with a web UI of some sort! Having to build a Go CLI tool in order to access it is a massive amount of friction.

I reverse-engineered it a tiny bit, looks like you can get a list of all builds so far like this:

  gsutil ls -r 'gs://google-rebuild-attestations/**'

I ran that and got back 9,507 - here's that list as a Gist: https://gist.github.com/simonw/9287de5900d5b76969e331d9b4ad9...
