For replacing Notion Kanban, maybe AFFiNE, that is mostly MIT license:

But some part of server code license may need checking:

Thanks for the suggestion, I love AFFiNE's approach, but for me it's just not there yet. I'm subscribed to their e-mail newsletter and check up on it from time to time, but for me personally it needs some more progress, e.g. a mobile version.
