reqres.in Features
One reusable REST API replaces the login, users, and CRUD backend you'd otherwise rebuild per project, cutting test setup from days to minutes.
Predictable REST Responses
Every endpoint returns fixed, versioned JSON so your test assertions never break from data drift.
Ready-Made Auth Flows
Register and login endpoints simulate token issuance without you standing up a real auth service.
Full CRUD Endpoints
Users and resources support GET, POST, PUT, PATCH, and DELETE out of the box for realistic test coverage.
Paginated List Responses
List endpoints return page metadata and per_page limits so you can test pagination logic directly.
Simulated Delay Endpoints
Trigger configurable response delays to test timeouts, loading states, and retry logic under real latency.
Deliberate Error Cases
Endpoints return specific 4xx and 5xx responses so you can assert failure handling without mocking servers.
CI-Friendly Uptime
A hosted, stable API means Playwright, Cypress, and Postman suites run the same in local and CI environments.
No Backend to Maintain
Skip building and hosting a throwaway CRUD server just to get realistic request and response data.
Request Logging on Demand
Inspect exact payloads and headers sent to each endpoint to debug client-side request construction.
Framework-Agnostic Fixtures
Point any HTTP client or test runner at the same endpoints for consistent fixtures across your whole team.
