Best is subjective and recommendations would depend on your use case. Iceraven is my primary.

They are not getting paid anything in this case. Usually they get paid by the state when doing work there, but since they were federalized they are under federal juridistion now and won’t get paid by the state for deployment. And Trump isn’t providing federal funds, hence them sleeping on the floor, having to pay for food themselves, using their own equipment.

Great admin team, public finances, reasonable rules, good defederation policy, data is hosted in the EU.

lemmy.zip would be my recommendation.

Since you deleted your post on !opensource@programming.dev, reposting my comment.

Another AI project that will probably be dead in a few months. Also open core not open source as many of the features are not available via self-hosted version.

Self-hosted version which source is available and hosted-version which is not public, are not the same. Or at the very least, planned to not be the same by your own admission as you talked publically about planning on adding paid-only features to hosted version.

Take out “AI features” and you are left with nothing, so yeah, AI project… It also relies on proprietary AI models that you don’t own, so it can stop working at any point and that would be out of your control.

EU has a similar program called Horizon Europe, which spent around €95.5 billion so far. Though it’s broader in scope, not limited to just software, but includes various open source research too.
