Mock APIs, Live Demos
Zero Infrastructure

The quick companion tool for developers. Perfect for testing, interviews, and rapid prototyping—no servers, no setup, just instant JSON endpoints.

Instant API Endpoints

Transform your JSON into live API endpoints in seconds. No server configuration, no deployment hassles.

  • Unique URL for every bin
  • RESTful HTTP responses with CORS enabled
  • Immediate availability—no waiting for deployments
  • Share endpoints via clean, permanent URLs

  "user": {
    "name": "Sarah Johnson",
    "email": "sarah.johnson@example.com"
  }

Dynamic Data Generation

Create realistic, randomized data with our token replacement system. Perfect for testing edge cases and simulating real-world scenarios.

  • 100+ token types for realistic data
  • {{random.name}}, {{random.email}}, {{random.uuid}}
  • {{random.number(min,max)}} for custom ranges
  • {{date.recent}}, {{date.future}} for timestamps
Input
Your JSON with tokens
{
  "user": "{{random.name}}",
  "email": "{{random.email}}",
  "id": "{{random.uuid}}",
  "score": "{{random.number(0,100)}}"
}
Output
Generated on each request
{
  "user": "Sarah Johnson",
  "email": "sarah.johnson@example.com",
  "id": "a7f3e9c1-4b2d-4e6f-9a8c-1d5e3f7b9c2a",
  "score": 87
}

Collections

Group related bins into collections for better organization. One bin can belong to multiple collections with our flexible many-to-many relationship system.

  • Many-to-many bin relationships
  • Project-based grouping
  • Easy bin discovery and management
  • Perfect for organizing team workflows
