There are lots of them out there to choose from. And being able to audit the secure portions is great, but a password manager is the perfect example of what free solutions often don't do well— you need to have a seamless experience across multiple platforms including mobile, and you need to have fairly deep integrations into multiple web browsers, which are notoriously fickle and need to be tracked closely.

The killer feature of 1Password (on Android at least) is that it comes up as a keyboard and can type long passwords into any apps. That seems like exactly the sort of fussy integration that would be really hard to build and maintain in something without commercial backing.
