Could you link some?

I mean, that sounds like a major claim, but it doesn't appear to be mentioned on either of their Wikipedia pages, in their FAQ's, nor on some of the top-results from Google.

For example, from [KeePassXC's "FAQ"](https://keepassxc.org/docs/ ):

> Why KeePassXC instead of KeePass?

> KeePass is a very proven and feature-rich password manager and there is nothing fundamentally wrong with it. However, it is written in C# and therefore requires Microsoft's .NET platform. On systems other than Windows, you can run KeePass using the Mono runtime libraries, but you won't get the native look and feel which you are used to.

> KeePassXC, on the other hand, is developed in C++ and runs natively on all platforms giving you the best-possible platform integration.

, where they don't appear to claim a security-advantage.

[This security-audit [PDF]](https://keepassxc.org/assets/pdf/KeePassXC-Review-V1-Molotni... ) claimed:

> It is interesting to notice, that the code of KeePassXC is organized in classes cleaner than the code of KeePass in C#. The classes are smaller, the functions are shorter. See e.g. the code to read a database. The reason for this might be that KeePass grew organically into a more complex logical structure and maybe it could enjoy some refactorings. In any case, right now, it is easier to review KeePassXC code for security and to understand it than to do so for KeePass.

, which seemed like a point in KeePassXC's favor.
