Been using the keepass format with varying applications for about 14 years. I used to host it in SVN repo for that sweet sweet cloud access! Not that smart im retrospec.. I feel like you shouldnt trust your passwords to the cloud, especially if their thing is password management. Last pass for example is under constant battery from attackers.
I personally use KeepassXC on my laptop and KeepassDX on my phone, and keep them synchronized with Syncthing. Works great, and no need for third-party / cloud storage!
