Accelerate Frontend Development with Realistic API Mocks

Generate realistic API endpoints in seconds. No more waiting for backend teams.

Why Use Spineless API?

Without Spineless API
  • Manually create mock JSON data
  • Set up local mock servers
  • Maintain mock data as requirements change
  • Development delays waiting for backend
With Spineless API
  • Define API schema once
  • Instantly get realistic mock data
  • Continue frontend development
  • Easily update as requirements change

How Spineless API Works

1
Define your API schema
Describe the data structure you expect
2
Get your endpoint instantly
A unique URL that returns AI-generated mock data
3
Build your frontend
Continue development without waiting
4
Switch to real API when ready
Simply change the endpoint URL
API Schema Definition
{
  "id": "string(uuid)",
  "name": "string(name)",
  "email": "string(email)",
  "role": "string(enum=admin,user,guest)",
  "isActive": "boolean",
  "joinDate": "date(iso)",
  "lastLogin": "date(recent)",
  "preferences": {
    "theme": "string(enum=light,dark,system)",
    "notifications": "boolean"
  }
}
AI-Generated Mock Response
{
  "id": "user_8f7d9b2a-e134-4dc3-b5e1-c1e7f3b0c8a9",
  "name": "Alex Johnson",
