After comparing several of these directories, seems https://euro-stack.com/ is the most comprehensive. I also like that it allows to filter by both being European and open source.
It is also made by the same people who run https://eurostack.eu/ and who got a lot of visibility delivering the https://euro-stackletter.eu/ letter to President Von der Leyen a year ago. Hopefully they settle soon on what is their primary domain :)
It is a screenshot of the filter option that allows to select both “European” and “open source” for people like who want both.
Ah, thank you for taking the time to write that down.
I should’ve written down my actual thoughts. The preview image didn’t look like it was from the site at all given how the search box is breaking the container, and that just looks off. I see now that it’s tailwind and indeed from that site. It is a little amusing to me that they’re using Tailwind since Tailwind Labs is a U.S. company.
