Question: The closest I was able to find is ***in Kürze***.

Is there a translation that means something similar as it does in English?

Answer: 
Your proposal *in Kürze* would likely be understood, but is mainly used for an event to happen shortly:

> 
> Hier eröffnet in Kürze eine Filiale von xxx. (here opens an outlet of xxx soon.)
> 
> 
> 

My proposal is:

> 
> kurz und knapp
> 
> 
> 

I had assumed it is a standing phrase, but Google hits are not so convincing.
It depends on how you use it.
But I want to add an other option to the already given answers.

> 
> kompakt
> 
> 
> 

It is often used for book titels.

**For example:**

> 
> Java in a nutshell
> 
> 
> 

**could be translated to:**

> 
> Java kompakt
> 
> 
> 

Because it is shorter than the other words, I would assume that this book is more straight forward and to the point. Also is sounds a little more professional to me.
