It it simply the best SEO URL Generator for OpenCart! It differs from many other modules in that it has redirect functionality. Also it is absolutely FREE!

But take attention that there is no mass generation of SEO URL in FREE-version. This feature is available in the paid version SEO URL Generator PRO.

Right now there are translit fucntions for:
Russian
Ukrainian
English

But in few days I will add:
Espanol
Bulgarian
Romanian
