Description
Intercept and modify HTTP requests & responses: URL redirects, headers, query params, and response body replacement. HTTP Interceptor is a developer-focused Chrome extension that intercepts and modifies HTTP requests and responses using an intuitive visual rule editor. Features: • URL Redirect — Replace host, path, full URL, or use regex-based URL rewriting. Preserve original paths and query parameters automatically. • Header Modification — Set, append, or remove both request headers and response headers. Perfect for adding Authorization tokens or CORS headers during development. • Query Parameters — Add, set, or remove URL query parameters on the fly. Useful for forcing debug mode or stripping tracking parameters. • Response Body Replacement — Find and replace text or regex patterns inside response bodies. Ideal for pointing frontend code to a different backend or modifying page content dynamically. • Flexible URL Matching — Supports wildcard patterns (*://example.com/*), exact URL matching, and full regular expressions. • Resource Type Filtering — Narrow rules to specific resource types such as XHR, scripts, stylesheets, images, and more. • HTTP Method Filtering — Apply rules only to GET, POST, PUT, DELETE, or other HTTP methods. • Import / Export — Share your rule configurations as JSON files with your team. • Dark Mode — Automatically follows your system theme preference. • Built-in Examples — Four pre-configured example rules demonstrate every feature so you can get started immediately. • Lightweight & Secure — Built entirely with Manifest V3 and Chrome's declarativeNetRequest API for maximum performance and security. All code is bundled locally, no remote code is loaded. Use cases: • Redirect API requests from production to your local development server • Add authentication headers to API requests during testing • Inject permissive CORS headers into responses for local development • Override query parameters for A/B testing or debugging • Mock or modify response bodies for frontend development • Remove tracking parameters (utm_source, fbclid, etc.) from URLs Privacy: This extension does not collect, store, or transmit any user data. All configurations are stored locally on your device using Chrome's built-in storage API.
