Do you know any good alternatives?

I've been able to submit new entries to

https://eucloud.tech/

https://buy-european.net/

I've also found other problematic ones:

https://euro-stack.com/ (I couldn't understand how to submit a new entry)

https://www.goeuropean.org/ (all submissions fail with an AirTable error [sic] that the workspace is at the record limit)
