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 API testing tool built around privacy, for developers who value simplicity and control. Use the web app in your browser, the Chrome and Firefox extensions, the Mac and iOS apps, or the CLI, all with no account.
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
- Collection variables: Use ${baseUrl} and ${token} across a collection's URLs, headers and bodies
- Script before and Script after: Automate workflows with JavaScript that runs before the request and after the response
- Response validation: Inspect headers, status codes, and response bodies
- Syntax highlighting: Beautiful JSON, XML, and HTML formatting
- Import and export: Share collections with your team
- Request history: Track all your API requests
Privacy first approach
HITOP stores all data on your device. Your API endpoints, authentication tokens and test data are never synced to a cloud. The web app sends requests to public APIs through the HITOP request proxy, which keeps nothing; the Mac and iOS apps, the CLI and the extensions send them straight from your device.
No account required
Start testing immediately without creating an account or providing an email. The web app works directly in your browser with nothing to install.
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.
