Request12 vs Edit HTTP Headers for Safari

Request12 is a focused API debugging tool built for iOS developers, QA engineers, and technical teams that need fast visibility into web traffic. Use the built-in browser to load a page, capture network calls, inspect details, and replay requests with edits in a sandbox environment. What you can do - Browse any target URL in an embedded webview. - Automatically capture `fetch` and `XMLHttpRequest` traffic from pages loaded in the app. - View method, status, timestamp, full URL, headers, request body, and response body. - Filter traffic by method and search by URL/status/error. - Inspect JSON with pretty print and syntax highlighting. - Copy URL, request body, response body, and payload sections in one tap. - Send captured requests directly to Sandbox. - Edit method, URL, headers, and body before execution. - Execute with cookie sync support from the browser context. - Review response status, latency, headers, and body for fast validation. - Switch between Light, Dark, and System themes. Request12 is designed for fast iteration: - Reproduce issues from real traffic. - Validate backend changes quickly. - Compare original vs modified requests. - Test custom headers and payload variations on mobile. Notes Request12 captures traffic generated inside the app browser context and sandbox workflow. It is intended for authorized testing and debugging use cases.
