Mocks straight from the spec
Auto-generate mock rules from your endpoints. One unique URL per project, ready immediately.
- Rules generated from the spec, customizable per endpoint
- Static responses: body, status code, headers
- Unique mock URL per project, CORS handled
Data that looks real
Realistic generated data, request variables, and state — responses that behave like production.
- Templates for realistic synthetic data — names, emails, addresses, and more
- Request variables like {{request.body.name}}
- Stateful mocks persist across a session
- Fixtures as response bodies, with transforms
Rehearse the bad days
Latency, errors, timeouts, rate limits — simulate the failures your frontend must survive.
- Fixed or random latency per rule
- 5xx responses, timeouts, connection resets
- Per-rule rate limiting
Proxy what you don't mock
Unmatched requests forward to the real API. Mock the new endpoint, proxy the rest.
- Proxy mode for unmatched requests
- Live request log for every mock call
One living spec
The rest of the lifecycle
Change the spec — everything on this page updates with it.
