DummyJSON Alternative — Multi-Protocol & Auth-Ready
DummyJSON is one of the cleanest free fake APIs around. This sandbox matches its CRUD ergonomics, then adds real auth, GraphQL, SOAP and Swagger so you can outgrow the fake.

Why most people switch
- They started practicing with REST and now want to learn GraphQL against the same data shape
- They need to demo a SOAP integration for an enterprise client
- They're building a real auth flow and need refresh tokens + role-based access
- Their integration tests need controllable failures (500s, timeouts) — not just success paths
Frequently asked questions
Will my DummyJSON code work with one base-URL change?
Mostly. Path shapes are similar but our success/error envelopes differ — most clients need a small response unwrap.
Is the data set as large as DummyJSON?
Smaller seed set, but you can POST as much as you like — your additions persist for 30 minutes per session.
