Future Fonts is a marketplace where type designers sell typefaces that are still being built, with specimens showing exactly how complete the character set, kerning, and weights are.
Buying in gets you the current work-in-progress file plus free updates as the designer finishes it, at a lower price than waiting for the finished retail release.
Interesting for designers who want to use something genuinely new before it's widely available, or who want to support an independent type designer directly.
This is paid - individual designers set their own prices, often discounted while the font is unfinished. There's no free commercial license here; each purchase covers just that one typeface.
