You can use "Anagrams generator" for free here

Try Anagrams generator with different words or names. Curious about even more original features? Then go to the awesome NameRobot Naming Toolbox, where there is Anagrams generator with all the trimmings. There are even more name generators and clever tools for word search, naming, and inspiration.

Use the Anagram Machine to shake up letters make new words. It works like this: You enter keywords and the tool tries to find words that contain exactly the same letters as the keywords used. This can be very helpful for finding a name, as the following example shows:

Mark wants to open a café. He enters the keywords Mark and Café. The generator generates the anagrams "Cake Farm" or "Mac Freak" - both made up of exactly the same letters as "Mark" and "Café". And bang! There you have the first ideas for a name for the café!

Anagrams don't always come up with suitable names, but it can be a lot of fun trying. So don't take the anagram search too seriously. :-)

You can fine tune the Anagram defaults in the Settings (Gear symbol).
