Free GM Resource: Abulafia Wiki (RPG Generators)
Abulafia is an...interesting random table generator in that everything is set up as a special Wiki page. You can navigate to the tables you want and just refresh the page to reset the tables and get new results.
While I find it a bit clunkier than dedicated table generators, the fact that it is basically a web page means you can use any browser to get some results. The wiki's built-in search feature is quite helpful as well.
Take Abulafia for a spin for yourself.
