Mock Server

MockServer is a free, hosted mock API server that lets developers spin up fake HTTP endpoints in seconds — no infrastructure needed.

Sign in with your Google, LinkedIn, or Microsoft account, choose your URL path and HTTP method (GET, POST, PUT, PATCH, DELETE, OPTIONS), write a JSON response body, set a status code, and your mock is live immediately under a personal slug-style URL (/mock/{your-slug}/{path}).

Key features:

Dynamic path parameters — define routes like /users/{id}/orders/{orderId} and inject the real values into your response payload Custom response headers — set any headers your frontend or tests need Simulated latency — add a delay (0–10,000 ms) to replicate slow network conditions Real-time traffic logs — every hit to your mock is recorded with method, headers, body, and IP for instant debugging Shareable mock links — generate a public share token so teammates can inspect your mock config without logging in JSON editor — built-in editor with syntax highlighting for authoring response payloads CORS ready — all endpoints return Access-Control-Allow-Origin: * automatically Caching — fast response times via server-side caching of mock lookups Ideal for frontend developers, mobile teams, and QA engineers who need a stable, controllable API stand-in during development or testing.
