Dicebear Avatars vs DummyJSON
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.
DummyJSON is a free, keyless REST API that serves realistic placeholder data — products, carts, users, todos, recipes, quotes, posts, and comments — with full CRUD support on every resource (writes simulate success but nothing is persisted). Query parameters cover pagination (limit/skip), field selection, sorting, and full-text search, and a dedicated /auth flow issues real JWTs against its seeded users so frontend teams can exercise login and token-refresh flows without standing up a real backend.
