What is a REST API client?
A REST API client is a tool used by developers to send HTTP requests to an API and inspect the responses. It helps in testing, debugging, and understanding how APIs behave in real-world scenarios.
Why use this API client instead of Postman?
Traditional tools like Postman require installation and sometimes login. This API client works entirely in your browser — no setup, no accounts, and no tracking. It’s fast, lightweight, and ideal for quick API testing.
How to use this REST API tester
- Enter the API endpoint URL
- Select the HTTP method (GET, POST, PUT, DELETE, etc.)
- Add headers or request body if required
- Click send and view the response instantly
Is this API client secure?
Yes. All requests are made directly from your browser. No data is stored, logged, or transmitted to any external server. This makes it a privacy-first alternative to traditional API tools.
