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. No credit card required.
