Wow, this looks really good at a glance and I will take a good look later, thanks!

EDIT: After a deeper look, I found some issues, like there are a lot of seemingly duplicate categories, (AWS [1] and Amazon Web Services [2]), but with different sets of results, which could be solved with normalisation, but then there are many "alternatives" shown that aren't EU-based, but OSS, like Gatsby [3] or NocoDB [4] and I'm not sure what to think. I think that's acceptable, but for OSS there are other lists I'd look into instead of a website/listing like this.

This is really nice, I appreciate anyone who will give more info out about it, I like the categories too, maybe some more tags would be nice for specifics but it's good. I also like you host in the EU too. I've seen some doing similar that were hosted in the AWS US region.

Nice!
