Significant parts of this website use brilliant open-source software developed by Ukrainians. Russia's unprovoked war has killed tens of thousands, displaced millions, and the beautiful country of Ukraine is being destroyed. We cannot be silent even if the topic of this website has nothing to do with politics.
