KeepassXC seems like the closest alternative to me. I'm evaluating that as a LastPass alternative - not because of the price increase (which isn't material) but because LastPass hasn't impressed me with their diligence and care regarding security, which is the whole point of a password manager, from my perspective.

But I'm delighted to hear of other alternatives if there's something better. I don't mind paying but I'm not going to pay for crap.
