This is the first I've heard about your event, or the preceding border:none ... despite living in Nürnberg and generally being on the lookout for English-speaking events.
I'll put both in my department's "General" Teams channel, as nearly half of us are not native German speakers - and most of the native German speakers are perfectly happy to get their web dev content in English.
The last border:none was 10 years ago IIRC. They are bringing all the same speakers back and some new ones.
A lot of IndieWeb events have been hosted in Germany.
There is an event called Beyond Tellerrand (btconf) hosted in Düsseldorf and Berlin every year, hosted by Marc and his amazing team (unaffiliated with Homebrew Website Club).
The IndieWeb sometimes hosts host events before or after Beyond Tellerrand conferences (I was at last year's Berlin btconf and IndieWeb event). I know it is a long journey from Nürnberg to those cities but both btconf and the IndieWeb events are both amazing ways to spend a few days if you love the web.
Most of our meetings are online now, but we have a longer, two-day in-person event coming up in Nürnberg at the end of October (https://events.indieweb.org/2023/10/indiewebcamp-nuremberg-2...).
