Mock REST APIs
For Rapid Integration.

Frontend developers shouldn't wait for backend infrastructure. MockForge gives you complete control over REST route creation, templating parameters, and latency rules.

GET/api/v1/users/:id/profile
Content-Type: application/jsonDelay: 1500ms
Custom Headers
Access-Control-Allow-Origin: *
Response Body Template
{
  "id": "{{request.params.id}}",
  "uuid": "{{uuid}}",
  "name": "{{faker.person.fullName}}"
}
DEVELOPER PAIN POINT

“We spent weeks writing placeholder server routes and syncing configurations across client repos. MockForge cuts that latency down to zero.”

The Slow Way

Frontend teams wait for backends to design database schemas, configure containers, and deploy dev builds. Any schema update triggers local code changes and communication overhead.

The MockForge Flow

Scaffold route structures on MockForge in seconds. Frontend developers design, test, and run client calls in parallel, syncing with standard schema specs immediately.

ENDPOINT DESIGNER

Curate every HTTP scenario.

Configure HTTP actions, return customized response headers, pick output formats, and copy dynamic testing commands straight from the table view.

MethodPath RouteContent-TypeActions
GET/api/v1/users/:id/profileapplication/json
POST/api/v1/orders/checkoutapplication/json
TEMPLATE ENGINE

Make mocks behave like a real backend.

Define response templates utilizing double-bracket parameters. Inject path variable parameters, request query configurations, timestamps, UUID values, or complete identities using our integrated Faker bindings.

Monaco Template Code
{
  "id": "{{request.params.id}}",
  "uuid": "{{uuid}}",
  "name": "{{faker.person.fullName}}",
  "email": "{{faker.internet.email}}",
  "status": "active"
}
Resolved JSON Payload
{
  "id": "42",
  "uuid": "79b3ea2b-9fca-44a5-9273-04b39178cc02",
  "name": "Jane Doe",
  "email": "jane.doe@example.com",
  "status": "active"
}
SSE DIAGNOSTICS & REPLAY

Diagnostics and Request Replayer.

Connect your mock routes to caller applications and monitor incoming calls in real-time. Use the logs request replayer sandbox to modify paths, methods, or bodies and send test dispatches instantly.
