About:
Requestly is a developer tool that intercepts and modifies HTTP/HTTPS requests directly from the browser or system. It allows users to redirect URLs, modify headers, inject scripts, and simulate API responses without backend changes. This streamlines debugging, testing, and frontend development workflows.
Key Features:
  • Intercept and modify HTTP requests on the fly
  • Redirect URLs and mock API responses
  • Modify headers, cookies, and API payloads
  • Script injection for custom logic
  • Cross-platform support (browser extension and desktop app)
Use Cases:
  • Debugging API issues by modifying request/response in real-time
  • Frontend development against mocked API endpoints
  • Testing edge cases and error scenarios without server changes
Alternatives:
  • Charles Proxy – Paid desktop proxy with deep network analysis; heavier than Requestly
  • Fiddler – Windows-focused proxy tool; less cross-platform than Requestly
  • Mock Service Worker – Code-first API mocking library; requires code changes vs Requestly's UI
