Unfortunately it doesn't show per 100K or # tested (which I would love to find, but haven't seen anywhere). The former should be quite easy to do, the latter appears to not be as easy to get good data for.
Also: made by one hacker!

For Germany I recommend:
crowd sourced from local data (faster than official, links to sources): http://www.risklayer-explorer.com/event/100/detail
New official from RKI, you can switch between levels of detail in the top left: https://experience.arcgis.com/experience/478220a4c454480e823...

You can also use https://outbreak.cc/canada.html, etc for some countries.
The stat I'm most interested in is daily new cases with fine granularity and for regions. I can't think of a clearer indicator of how well we're dealing with containing it.
The people behind https://covid19.fyi/ have been open-sourcing it (http://github.com/COVID19-OSS/ - I'm a contributor), and it's also pretty solid, although lagging behind right now.
Unconventional, but very useful.
