Is there a free version of Aeonik?

No. Aeonik is a paid sans serif from CoType Foundry. Every alternative on this page is free for commercial use, under the SIL Open Font License.

How were these alternatives chosen?

By measuring the letters, not by comparing names or tags. Aeonik was measured as cotypefoundry.com draws it: its proportions, the width of every letter and figure, its weight, its stroke contrast and the shapes of telling letters like a, g, R and Q. The same measurements were taken of 1,506 free fonts, and these came closest. Each match was then checked by eye.

Will Open Sauce One change my layout?

Not if you use the CSS on this page. It sets Open Sauce One 7.8% smaller, so text written for Aeonik keeps its x-height and its line lengths, and lines break in the same places.
