UI Faces is a small library, 321 AI-generated avatar images across five categories (Human, Alien, Cartoon, Abstract, and a curated "Popular" pick), built specifically to fill in placeholder faces in mockups.
Because the faces are AI-generated rather than photos of real people, there's no likeness or model-release question hanging over using them in a mockup.
Fits the specific job of populating a comment thread, testimonial section, or user list mockup with varied-looking faces fast.
Individual avatars are free to grab; the full 321-image ZIP is a $3 one-time purchase, more a convenience fee than a real paywall.
