MockServer.in

About MockServer.in

MockServer.in generates a callable HTTP mock endpoint from pasted JSON, with no signup, no install and no config file. You choose a status code, paste a response body, hit generate, and get a real URL you can curl, point Postman at, or wire into a frontend that is waiting on a backend nobody has written yet. The quick-mock path requires no account at all and the endpoint lives for 72 hours; signing in raises the limits and adds persistence. Beyond the basic happy path it simulates the conditions that actually break client code: configurable latency ranges so you can see what a slow dependency does to your loading states, and failure simulation so error handling gets exercised before production does it for you. Traffic logs show each hit against a mock with a hit counter returned in the response headers, and a version history keeps prior response bodies so you can roll a mock back after editing it. It positions itself as a lighter alternative to Beeceptor, Mockoon and Postman mocks — no YAML, no Docker, no local server. Around the core product sits a set of browser-only developer utilities that never send data anywhere: an API tester, cURL-to-code, regex tester, cron parser, epoch converter, UUID and hash generators, a JSON formatter/validator/repair suite, JWT decoder and Base64/URL encoders.
