Core Features
Everything you need to accelerate frontend development
Instant APIs
One-click creation of an API endpoint with a random unique URL. No login or setup required - start testing in seconds.
Scripting Engine
Write custom logic in TypeScript to dynamically generate responses based on the request data, simulate errors, and add realistic behavior.
Request Inspector
See each request's details (method, path, headers, body) and the corresponding response in real-time through an intuitive dashboard.
Debugging Breakpoints
Set up interception rules to pause specific requests. Modify the request or response on the fly for true breakpoint debugging.
TypeScript Client
Generate fully-typed TypeScript client libraries from your API. Get autocompletion, type safety, and validation right in your IDE.
OpenAPI Import
Import OpenAPI/Swagger specs to instantly generate a complete API based on your schema. Customize the responses as needed.
And Many More Features
Designed to make your development experience seamless
Disable Caching
One-click option to disable caching, ensuring your API always returns fresh responses without browser caching interference.
Team Collaboration
Share APIs with your team, collaborate on API definitions, and streamline your development workflow together.
Multiple Environments
Create and manage multiple APIs for different projects, teams, or environments from a central dashboard.
CLI Integration
Use our command-line tools to create, update, and manage your APIs directly from your terminal or CI/CD pipeline.
Data Persistence
Store and retrieve data across requests, enabling true CRUD operations and stateful APIs for end-to-end testing.
Custom Latency
Simulate network conditions by adding configurable delays to your responses, perfect for testing loading states.
Import/Export
Easily migrate your API configurations between environments with comprehensive import and export tools.
Custom Domains
Map your own domain to your APIs for a more professional setup in test environments and demos.
Smart Generation
Use AI to generate realistic data based on your API schema, making your test data more representative.
Validation Rules
Define validation rules for incoming requests to test how your frontend handles API validation errors.
Proxy Mode
Selectively proxy requests to a real backend while simulating others, enabling partial simulation of existing APIs.
Request Recording
Record real API interactions and replay them later, making it easy to create realistic test scenarios.
How It Works
A seamless workflow from development to production
1. Create Your API
Click a button and instantly get a unique API endpoint. No signup required. Your API is ready to use immediately.
2. Customize Responses
Define custom endpoints, status codes, and response bodies through our intuitive dashboard. Use scripting for dynamic behavior.
/users/13. Debug & Improve
Use the request inspector to view all incoming requests. Set breakpoints to pause and modify responses for complete control over your API behavior.
4. Collaborate
Share your API with teammates. Everyone can see the same endpoints, inspect requests, and make improvements together.
