UMT..MIRACLE..QCfire..BEST SMART tool

Hi
I Just Would like to know if there are any Standalone Tools that Works without Box or Card or Dongle that Can Be Downloaded for free Like
UMT...MIRACLE Box..QCfire...BEST SMART Tool or any other similar.
Everytime I fould one of these and the Page Says it Works alone.. either on Google or youtube it directs you to a Multiple sites and even if you can Download it
is either detected as a Virus by Avast or it Doesen't work for 1 reason or another.
Does it Mean that it doesen't Exist unless you buy the Hardware?
Can Anybody Help me and give some Answer.
Thank you
