Kratos and Better Auth are almost orthogonal to one another. Kratos provides a comprehensive back end, but no front end at all - you have to write it yourself.

Better Auth is mostly focused on the front end.

You could use the two together, although I haven't seen anyone do that.

I have wasted so much time on third-party authentication frameworks like Ory Kratos that I wish we'd just written our own internal auth library. With Kratos we ended up customising it so heavily we could have just written our own. Same goes for ones that provided a frontend such as Keycloak.

I addressed that here, straight from the article. Basically open-core and hosting.
