What is an API Testing Tool?
An API testing tool is software that helps developers test, debug, and validate Application Programming Interfaces (APIs). These tools enable you to send HTTP requests, inspect responses, manage test collections, and automate API workflows.
Why Choose HITOP as Your API Testing Tool?
HITOP is a modern, privacy-focused API testing tool designed for developers who value simplicity and control. Unlike traditional tools, HITOP runs entirely in your browser with no account requirements.
Key Features
- Complete HTTP Support: Test GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS requests
- Request Collections: Organize your API tests into collections for better management
- Environment Variables: Use variables to manage different environments (dev, staging, production)
- Pre/Post Request Scripts: Automate workflows with JavaScript scripting
- Response Validation: Inspect headers, status codes, and response bodies
- Syntax Highlighting: Beautiful JSON, XML, and HTML formatting
- Import/Export: Share collections with your team
- Request History: Track all your API requests
Privacy-First Approach
HITOP stores all data locally in your browser. Your API endpoints, authentication tokens, and test data never leave your machine. This makes it perfect for testing internal APIs and sensitive projects.
No Account Required
Start testing immediately without creating an account, providing email, or installing software. HITOP works directly in your browser.
Common API Testing Scenarios
REST API Testing
Test RESTful APIs with full support for JSON payloads, query parameters, and authentication headers. HITOP makes it easy to validate REST endpoints.
Authentication Testing
Test APIs with various authentication methods including Bearer tokens, Basic Auth, API keys, and custom headers.
API Development
Use HITOP during API development to quickly test endpoints, validate responses, and debug issues without switching tools.
API Documentation
Create collections that serve as living documentation for your APIs. Share them with team members or clients.
Getting Started with HITOP
HITOP is an open-source API testing tool that requires no installation. Simply launch the web app and start testing your APIs immediately.
Comparison with Other API Testing Tools
HITOP offers several advantages over traditional API testing tools:
