DummyJSON vs What The Commit

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.

What The Commit serves an endless stream of joke commit messages drawn from a fixed pool, built to be piped into git commit -m when you can't think of anything better. The plain-text /index.txt endpoint returns one message per request for shell scripting and git aliases, and a live /index.json endpoint wraps the same message with a stable hash and permalink. It's free, keyless, and carries no rate limit or pricing page.
