Reqix: Intercept, Modify & Mock HTTP Requests, Inject Scripts

Description

Intercept and modify Fetch/XHR requests, mock APIs, redirect URLs, and inject page scripts—all locally. Reqix is a local-first web request debugging and page scripting tool. Without changing application code or configuring a system proxy, you can intercept and modify Fetch/XHR requests, mock API responses, redirect URLs, simulate error conditions, and run custom JavaScript or CSS on matching pages. 🚀 Core Capabilities 👉 Request Interception & Modification → Add, modify, or remove request headers → Edit query parameters and JSON request payloads → Modify response bodies, status codes, and response headers → Add response delays to simulate slow networks → Cancel matching network requests → Match rules by URL, HTTP method, and page scope 👉 API Mocking & Dynamic Responses → Return custom responses for Fetch/XHR requests → Continue frontend development before backend APIs are ready → Use JavaScript to generate dynamic responses from request data → Simulate 4xx, 5xx, empty-data, malformed-response, and timeout scenarios → Debug REST, GraphQL, and other APIs built on Fetch/XHR 👉 URL Redirects & Environment Switching → Redirect APIs, scripts, stylesheets, images, and other resources → Switch resources between development, staging, and production environments → Preserve or replace original query parameters as needed → Test local or staging resources on live pages without changing application code → Handle the request rules required for cross-origin redirects 👉 Page Scripts → Run custom JavaScript on matching websites → Match pages using exact URLs, contains rules, wildcards, or regular expressions → Configure excluded URLs, iframes, and execution timing → Run scripts at page start, after DOM readiness, or when the page becomes idle → Choose between an isolated environment and the page’s JavaScript context → Modify the DOM, inject CSS, add debugging helpers, or automate repetitive actions → Import .user.js, JavaScript files, and Tampermonkey JSON/ZIP backups → Batch enable, disable, import, export, or delete scripts 👉 DevTools Request Debugging → Capture Fetch/XHR requests directly in DevTools → Search, filter, and inspect request and response details → View the final data after matching rules are applied → Create individual or multiple rules from captured requests → Open and edit the matched rule directly from a request 👉 Rules & Data Management → Organize rules into groups for different projects or environments → Control the extension, individual sites, groups, and rules independently → Detect potentially conflicting request rules → Review rule hits and processed request results → Import or export rules, groups, and page scripts → Keep core configurations and debugging workflows local 🌟 Common Use Cases → Mock API responses before the backend is available → Test empty states, error responses, delays, and edge cases → Debug request headers, query parameters, payloads, and authentication data → Redirect production requests to development or staging environments → Test local scripts, styles, or resources on live pages → Inject debugging utilities, visual markers, or automation scripts → Create rules quickly from real network requests → Reproduce and diagnose issues without modifying project code Reqix brings request interception, API mocking, URL redirects, error simulation, page scripts, and DevTools workflows together in one clear and modern interface—helping web developers and QA teams debug faster with less setup. 🏡 Website https://reqix-dev.github.io/reqix-website/ 📖 Documentation https://reqix-dev.github.io/reqix-website/docs/ 💬 Community Discussions https://github.com/reqix-dev/reqix/discussions 📳 Issues & Feedback https://github.com/reqix-dev/reqix/issues 🔒 Privacy https://reqix-dev.github.io/reqix-website/privacy/
