Mock API
Create a Mock API in Seconds
Forge API lets you create working API endpoints without building a backend first. Choose an HTTP method, enter an endpoint path, paste your JSON response and receive a hosted API URL that your application can call immediately.
No backend server setup required.
✓
Start frontend development before backend work is complete.
✓
Return your own JSON response from a real hosted endpoint.
✓
Test loading, success, empty and error states.
✓
Replace only the base URL when your production API is ready.
How it works
From JSON to a working endpoint
2
Add your JSON
Paste the exact JSON response your frontend expects from the future backend.
3
Use the generated URL
Connect the hosted Forge API endpoint to your frontend and continue development immediately.
Use cases
Built for practical development workflows
Frontend development
Build pages and application flows while the production backend is still being designed.
API demonstrations
Create predictable endpoints for product demos, prototypes and stakeholder presentations.
Automated testing
Use controlled JSON responses to test success, failure and edge-case behaviour.
Frequently asked questions
Questions about mock api
What is a mock API?
A mock API behaves like a real API but returns predefined responses. It allows frontend development and testing to continue before the production backend is available.
Can I create custom JSON responses?
Yes. Forge API allows you to define the JSON returned by each endpoint.
Do I need to run my own mock server?
No. Forge API hosts the endpoint for you and provides a URL that can be used from your application.
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.
