I hacked together a web-index for the CKAN where you currently can just view all entries from the main CKAN-repository in better-readable format than JSON.
You can try the new (rewrite) version on https://brohlsoft.de/apps/ckan/
As a side-effect I am mirroring the main CKAN index dump (lagging behind some hours) at https://brohlsoft.de/apps/ckan/latest.tar.gz
For the old version, sources are available (but not very pretty) on https://bitbucket.org/janbrohl/ckan-web license is BSD-3-clause
