We're on the process of migrating from LastPass to self-hosted Psono[0]. I've not yet used Psono enough to say anything except that it seems better than LastPass, but that's not a hard goal to reach. With LastPass the whole UI/UX seemed awfully complex and cluttered and devoid of many handy QoL features like copying a password straight to clipboard. Their Chrome extension is also a true heavyweight[1].
