I've just switched from 1password to keepassxc in the past few weeks. The only reason I did so was because 1password was trying to force me into their subscription service as I switched from macOS to linux mint. I looked at a few work-arounds on github, but eventually just decided to move over to keepassXC.

The export / import and overall setup was pretty painless. I am still able to sync through dropbox just like with 1password. There is also an ios app called keepasstouch which was a breeze to get going and syncs with my dropbox password vault. Finally, the browser extension works in a very similar way to 1password's.

Overall, I definitely recommend it. I haven't lost any functionality or security to my knowledge. I was happy to pay up front for 1password (probably dropped 60-80$ or so for their apps), but, after doing so, just couldn't stomach being forced into their SaaS model. Especially when a similar free, open-source alternative exists.
