I'll share the one I contribute to - https://stopify.org.ua/

I like the subscription concept here - monthly donations, set to stop the moment Ukraine wins. Because they need our help continuously, not just after a particularly bloody episode makes the news.

It's ran by ziedot.lv - the organisation that handles most of charitable donations in Latvia.

Glad you shared, I was wondering about the same. Many of my donations are going to support various drone campaigns from Estonia in support of Ukraine https://www.help99.co/patches

And the amazing team at https://savelife.in.ua/en/
