Frontend development
Ship features before the backend is ready
Frontend teams shouldn't be blocked waiting for backend APIs. Mockra turns any OpenAPI spec into live mock endpoints in seconds — so you can build, review, and merge without the dependency.
The problem
- ✕Backend APIs aren't ready when frontend sprints start
- ✕Hardcoded mock data gets out of sync with real schemas
- ✕PRs sit blocked waiting for an endpoint that doesn't exist yet
- ✕Every developer maintains their own local mock setup
- ✕Integration surprises appear only when APIs finally ship
With Mockra
- ✓Upload the agreed OpenAPI contract on day one of the sprint
- ✓Live mock endpoints are available to every developer immediately
- ✓Response bodies, status codes, and shapes match the real spec
- ✓One shared mock URL — no per-developer setup required
- ✓Integration works on day one because the contract was always honoured
From spec to shared mock in under a minute
STEP 01
Upload the agreed API contract
Drop in the OpenAPI spec (YAML or JSON) your backend team is building to. Mockra parses it and generates mock endpoints for every path immediately.
curl -X POST https://api.mockra.io/workspaces/my-workspace/schemas \
-H "Authorization: Bearer <token>" \
-F "file=@openapi.yaml"
STEP 02
Point your app at the mock URL
Every endpoint is live at your namespace URL. Set it as your API base URL in development — no proxy, no setup, no per-developer config.
# .env.development
NEXT_PUBLIC_API_URL=https://mock.mockra.io/acme
STEP 03
Customise responses as needed
Edit response bodies, status codes, and shapes from the dashboard. Simulate error states, empty collections, or edge case payloads your UI needs to handle.
PUT /mock-configs/:id
{
"status_code": 422,
"body": { "error": "email_taken", "field": "email" }
}
