Reqtor

Reqtor is a fast, lightweight, and developer-focused API testing tool designed for Android. It helps developers, QA engineers, and backend testers create, organize, and debug HTTP APIs directly from their mobile device. 
Reqtor supports all common REST methods including GET, POST, PUT, PATCH, and DELETE. You can easily configure request headers, query parameters, request bodies, authentication values, and custom User-Agent strings using a clean and intuitive interface. 
To improve productivity and reduce repetitive work, Reqtor allows you to group APIs into collections, re-run requests from history, and inspect responses in detail. Each response includes HTTP status codes, headers, response time, and a formatted body for better readability. The app includes essential JSON tools, such as: * JSON viewer with proper formatting * JSON comparison to identify differences between responses * Easy copy and reuse of JSON data
 Reqtor is built with a developer-first mindset: * Minimal and distraction-free UI * Fast execution and low memory usage * Reliable behavior even with large responses * All API data stored locally on the device by default

 Multi-language support Reqtor supports multiple languages to provide a comfortable experience for users across different regions. The app is localized for users in: * Americas and Europe * Asia-Pacific * India * Middle East This ensures better accessibility and usability for a global developer audience, regardless of their preferred language.
 Privacy and security Reqtor does not upload your API data by default. Requests, collections, and history remain on your device unless you explicitly choose to share information. This makes it suitable for testing internal, staging, or development APIs. Whether you are debugging backend changes, validating API responses, learning REST concepts, or testing services on the go, Reqtor provides a focused and dependable API testing experience on Android.
