API Mocking
API Mocking for Development and Testing
API mocking removes the dependency between frontend and backend development. With Forge API, your team can create stable hosted endpoints that imitate expected production responses while backend services are incomplete or unavailable.
No backend server setup required.
✓
Develop frontend and backend systems in parallel.
✓
Create predictable responses for repeatable testing.
✓
Reduce delays caused by unavailable services.
✓
Demonstrate complete user flows before production integration.
How it works
From JSON to a working endpoint
2
Create the mock
Save the response as a hosted Forge API endpoint.
3
Switch later
Replace the Forge API base URL when your real backend becomes available.
Use cases
Built for practical development workflows
Parallel development
Allow frontend engineers to progress independently from backend delivery.
Failure simulation
Prepare responses representing missing data, failed requests and unusual conditions.
Product prototyping
Build functional prototypes using realistic network requests rather than hard-coded local data.
Frequently asked questions
Questions about api mocking
Why use API mocking?
API mocking reduces development delays and provides predictable data for development, demonstrations and testing.
Is API mocking only for frontend developers?
No. It is also useful for QA teams, mobile developers, product designers and backend engineers testing integrations.
Can a mock API replace a production API?
A mock API is mainly intended for development and testing. Production systems should normally use a real backend with persistent data and business logic.
Build your frontend before the backend is ready
Create custom mock endpoints, return your own JSON and connect your application to a working API URL in seconds.
