Desura Free Game Grabber

Always dubious of installing anything that claims to get me things for free as they usually have hidden nastys in them.
Running the client isn't that much of a problem anyway, so will stick with that.

Its fine you can see the code here: https://greasyfork.org/en/scripts/7338-desura-free-game-grabber/code

Thanks. this is great, especially as there are no official Linux client anymore

Another option without the client or any third party software:

Go back to the home page, search the game and when it appears, hover it. There is a "Add to collection" button.

i installed tampermonkey and the script now how exactly do i run it

Would be even nicer to have a script to just add all games that are free automatically (which i confused the title with).
I made a list with clickable links for most of the free games (though might not be up to date).
