ReqRes
Hosted REST API for testing, prototyping and learning, with real endpoints, persistentdata
ReqRes is a hosted fake REST API that provides real endpoints, persistent custom collections, authentication flows, and request logs, so developers can build and test against a backend without deploying or maintaining one. It supports GET, POST, PUT, PATCH, and DELETE operations with realistic JSON responses and proper HTTP status codes, along with login and registration endpoints that return tokens and error states for testing auth flows.
Core capabilities include custom collections with data that persists between sessions, request logs for inspecting traffic, latency and error simulation via query parameters, and an agent sandbox (/agent/v1) offering deterministic seeded data, failure scenarios, and a payments sandbox for AI coding tools. It integrates with testing frameworks such as Playwright, Cypress, Postman, and REST Assured, and works with frontend and mobile platforms including React, iOS, Flutter, and React Native.
ReqRes is aimed at frontend and mobile developers, QA and test-automation engineers, educators, teams running CI pipelines, and AI agent developers. It is packaged as a freemium, month-to-month service: a free tier with a daily request limit and an API key, individual editions (Lite, Dev, Pro) with higher limits, persistent collections, and request logs, plus Team, Agent Developer, Agent Platform, and Enterprise plans with shared projects, scoped keys, and custom limits. A commercial licence covers workplace use.
