Dicebear Avatars vs RandomUser
DiceBear is a free, open-source avatar library exposing a keyless HTTP API: request https://api.dicebear.com/{version}/{style}/{format}?seed=... and get back a deterministic avatar built from 35+ styles, from pixel-art robots to human illustrations. The same seed always renders the same image, making it a natural default profile picture for users who haven't uploaded a photo, and the whole engine — plus JS, PHP, Python, Rust, Go, and Dart libraries — can be self-hosted for private or commercial use.
RandomUser (the Random User Generator) is a free, open-source API that returns one or more fully-formed fake user profiles — name, address, email, login credentials, and photo — as JSON, XML, CSV, or YAML depending on the format query parameter. Requests can be tuned with parameters for results count, gender, nationality, and a seed value that makes the "random" output reproducible across calls. It has no authentication and no key-based rate limit, making it a common stand-in for Lorem Ipsum-style placeholder people in demos and test fixtures.
