Unique Letters:

This anagram generator is designed to find fun, interesting (and sometimes higly offensive) anagrams, and do it in as little time as possible. Its search algorithm is by no means exhaustive since its purpose is not to find all the anagrams that exist for certain phrases, especially the longer the inputs get. Instead, it will find a random subset of them within a time budget and then score them according to how useful the words that form each anagram are. The results are then presented in descending order of their score.

Created by TurboSplash and inspired by the anagram server on Anagram Genius, now defunct and 503'ing for months.
Their API has provided lots of fun over the years and good alternatives don't seem to exist, especially ones exposing an API.
Even if it probably wasn't going to be as good, I decided to just write my own, and I think it's pretty close.
