Monitor network requests and API failures with real-time insights 🚀 RequestScope – The Ultimate Network Monitor, API Debugger & Analytics Tool for Web Professionals! RequestScope is a professional-grade Chrome extension designed for developers, QA engineers, product managers, and advanced users. It seamlessly monitors, analyzes, and mocks network requests directly from your browser—without needing external tools like Postman or Charles Proxy. Whether you're debugging elusive API failures, optimizing page load times, mocking responses for UI testing, or analyzing third-party tracking scripts, RequestScope gives you unparalleled visibility into the network layer. 🎭 Intelligent API Mocking – Intercept and mock API responses on the fly. Test different UI states, error handling, and edge cases instantly without changing backend code. 🤖 AI-Powered "Hostile Roasts" – Get your website's performance and network health hilariously roasted (and critiqued) by AI based on real-time data! 📊 Full Payload Capture Details – Inspect request bodies, response payloads, hidden headers, and timing metrics in a clean, syntax-highlighted UI. 💾 Persistent Session Storage – Network history is preserved securely across browser restarts. Close Chrome and come back later without losing your session data! 🔍 Smart E2E Navigation Grouping – Requests are logically grouped by "Previous Load" and "Current Load", so you know exactly which actions triggered which API calls. 🛠️ Advanced API Debugging & Inspection Monitor all XHR, Fetch, Script, Document, Image, and Web Socket requests. Instantly identify 4xx and 5xx errors with color-coded alerts and visual UI indicators. Deep-dive into request and response bodies (JSON, Text, Form Data, URL params) with syntax highlighting and automatic formatting. Compare differences between two similar requests with built-in diffing tools. ⏱️ Performance & Speed Optimization Analyze page load times with precision metrics (Navigation Timing API & Fallbacks). Identify the top 10 slowest endpoints dragging down your application's UX. Monitor "Time to First Byte" (TTFB) and total request durations to optimize your Critical Rendering Path. 📈 Intelligent Analytics & Reports Generate comprehensive, shareable HTML Performance Reports with a single click. View total bandwidth weight, success/error ratios, and resource categorization charts. Track analytics across all domains with the "Full History Archive" or isolate data to the "Current Page". 🎯 Laser-Focused Filtering & Allowlisting Cut the noise. Use powerful allowlisting and domain targeting so you only capture requests for the websites you actually care about. Mute specific URLs, noisy analytics trackers, or third-party ads to keep your logs clean. Advanced Regex and glob pattern support for ultimate control over what gets captured. 🔔 Real-Time Toaster Notifications Get unobtrusive, in-page toaster alerts the exact millisecond an API fails or a request is dangerously slow. Configure custom thresholds (e.g., alert me if any request takes > 3 seconds). 🛡️ Privacy-First & Secure Runs entirely locally in your browser context. We do not track you, we do not collect telemetry, and your data never leaves your machine. All request history is stored securely using browser-native IndexedDB and Extension Local Storage. 👨💻 WHO IS REQUESTSCOPE FOR? Frontend Developers: Mock APIs while the backend is still being built. Debug CORS errors, missing headers, and malformed JSON payloads instantly. Backend Developers: Verify that your endpoints are returning the correct data shapes and HTTP status codes in the wild. QA Engineers & Testers: Capture E2E test failures, export HAR files or Postman collections, and attach full network traces to bug reports. Product Managers & SEO Experts: Monitor third-party script bloat, track page load speeds, and verify analytics firing correctly. 💡 HOW TO USE IT Install RequestScope. Click the extension icon to open the popup. Add your target website domain (e.g., localhost or yourdomain.com) to the Allowlist in Settings. Browse your site! RequestScope will silently capture, categorize, and analyze the traffic. Click any request to view full details, mock the response, or generate a final report. ⚡ Stop guessing why your web app is broken. Start debugging with precision. Install RequestScope today!
Moqyy — API Mocking & Fetch/XHR Interceptor
Mock APIs, intercept fetch/XHR requests, and test frontend apps without backend. Built for frontend developers and QA testers. Moqyy is the easiest way for frontend developers and QA testers to mock API responses and intercept network requests inside the browser. Mock APIs instantly, intercept **fetch** and **XMLHttpRequest (XHR)** calls, and test your frontend without waiting for backend endpoints. Moqyy is lightweight, fast, and built specifically for modern frontend workflows (React, Vue, Next.js, Angular). Key features • Intercept **fetch** and **XHR** calls. • Create API mock rules in one click. • Auto-fill request/response patterns and templates. • Save mock rules locally and import/export JSON. • Enable/Disable mocks globally or per-rule. • Capture real responses to use as a mock (Auto-capture). • Test different server responses (200, 400, 500, custom JSON). • Lightweight extension that won’t clutter your devtools. Who should use Moqyy • Frontend developers building UI without backend readiness. • QA teams testing client behavior for edge/backend error states. • Engineers who need fast, local API mocks without complex setup. Quick start 1. Install the extension. 2. Open the Network tab in Moqyy and trigger a fetch/XHR from your app. 3. Click the “+” next to a request to create a mock. 4. Edit the mock response and enable it — refresh your app and see the mocked response in action. Why Moqyy vs other tools • Focused on **API mocking** for frontend workflows (not a general network toolbox). • Simpler onboarding and a modern UI that developers prefer. • Built for speed — create useful mocks in under 30 seconds. If you find issues or want features, use the in-extension Feedback button — we read every message.
