Mock Server

Every frontend developer hits the same wall — the backend isn't ready, but you need a real endpoint returning realistic data right now. mockserver.in solves this in under 60 seconds. Describe your endpoint in plain English, paste a schema, or fill a form — AI generates a realistic mock response and gives you a live URL immediately. No install. No YAML. No Docker. No config files. What makes it different: - AI-generated responses — describe your endpoint, get realistic JSON back instantly - Real-time traffic logs — see every incoming request with full headers, body, and timestamp as it hits. Useful for debugging exactly what your app is actually sending - Intermittent failure simulation — fail X% of requests to test your retry logic and error handling - Dynamic path params — use {id} or {slug} in your route, the real value gets injected into the response automatically - Response delay simulation — test how your UI handles slow or timing-out APIs - Shareable links — one URL your whole team can hit, whether they're on web, iOS, or Android - 1-click signup via Google or GitHub Free for up to 20 mocks.
