Fonts like SF (san francisco) or Myriad Pro free for commercial use?

Question

Google Fonts

I am developing a website, I need an inexpensive (and preferably completely free) web font with a license-permission for commercial use, and a variant that looks just as good in Light as the above two
Ps fonts Do not offer accordions like Tahoma-Verdana-Times-Georgia-Arial ) Thank you!)
Regards.

Answer 1

Free:
Open Sans may resemble Myriad Pro in character, from afar, of course... Source Sans is also there (author - Adobe, by the way, but also free)
Roboto is a great font, but it doesn't match SF and MP at all in character. However, it can be replaced with SF if you want to create a slightly stricter and more conservative mood (as opposed to friendlier fonts like Open Sans)
