Frequently asked
Is reqres.in free to use?+
Yes, the public API is free for testing and CI use. No signup, no API key, no rate-limit surprises for standard test suites.
Do I need to set up a server to use this?+
No. Point Playwright, Cypress, or Postman at our hosted endpoints and start sending requests immediately.
How long does onboarding take?+
Under five minutes. Copy an endpoint URL into your test config and run your first request.
Is the data real or does it reset?+
Responses are predictable mock data, not persisted user records. Same request, same shape, every time — built for repeatable test assertions.
Can I use this for CI pipelines?+
Yes. The endpoints are stable and rate-limits are generous enough for parallel CI runs across GitHub Actions, GitLab CI, or Jenkins.
Does this replace building my own CRUD + auth backend?+
For testing purposes, yes. You get login, list, create, update, and delete endpoints out of the box instead of scaffolding a new backend per project.
What about data privacy — is my test data exposed?+
Since responses are static mock data, there's no real user data to leak. Don't send production credentials or PII through the API.
Does it integrate with Postman and Cypress directly?+
Yes. Import the endpoints into a Postman collection or reference them directly in Cypress fixtures and intercepts.
Can I cancel or stop using it anytime?+
There's nothing to cancel — no subscription, no lock-in. Remove the endpoint from your config and you're done.
What if the API goes down during a demo or CI run?+
Uptime is monitored and endpoints are cached at the edge, but treat this as a testing tool, not a production dependency.
Does this handle authentication flows too?+
Yes. Login and register endpoints return tokens so you can test authenticated request flows without building an auth server.
Why not just mock the API myself with a tool like MSW?+
You can, but that means writing and maintaining fixtures yourself. This gives you a hosted, consistent contract your whole team can point to without local setup.
Ready to get started?
One reusable REST API replaces the login, users, and CRUD backend you'd otherwise rebuild per project, cutting test setup from days to minutes.
