Some of the information on there is useful, but I'd say that alternativeto.net is an almost perfect example of a bloaty & hostile website. OP's website is much more pleasant.
Seems it's always the same trade-off: either a commercial site with an opaque business model, or a weekend passion project which might go away when the hobbyist in question finds they have other (or more lucrative) things to do.
Alternativeto was a site I used to frequent, but after their redesign, it’s been pretty painful to use and a lot less valuable.
SaaSHub founder here. Have you tried https://www.saashub.com? It has both "open-source alternatives" and "EU Alternatives".
In most cases I’m looking for alternatives to local apps, rather than a SaaS offering.
The most bewildering thing about the redesign is that the button to visit an application's website -- arguably the most important one since one would assume people are on the site to try out alternatives -- is now hidden somewhere far below the fold.
