Random User APIs
Random user APIs generate fake people for seeding databases and filling UI mockups. RandomUser is free and keyless, returning names, addresses, photos and login details. Random Profiles goes wider with 100+ fields per profile plus company records, while Randommer, a freemium keyed API, also produces phone numbers, text and hashes. ReqRes serves fixed fake users inside a hosted mock REST API for QA work.

Choosing a Random User API
Is there a free Random User API?
Yes. RandomUser and Random Profiles are free to use, and Randommer and ReqRes have a free tier alongside paid plans.
Which Random User APIs work without an API key?
RandomUser and ReqRes need no key or sign-up, so you can try them with a plain request.
Can I call a Random User API from front-end JavaScript?
RandomUser and ReqRes allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.
Can I use Random User APIs in a commercial project?
Random Profiles permits commercial use. ReqRes restricts it, for example to non-commercial or attributed use, so read the terms first.
Which Random User APIs work with AI agents?
Random Profiles has both an MCP server and an OpenAPI spec. Randommer publishes an OpenAPI spec for generating clients and tools.
