Very helpful with simulating errors

Mehmet Sert2025年7月24日

Harika. Modify API Response özelliğini çok sık kullanıyorum işlerimi pratik bir şekilde yapmamı sağlıyor. Modify API Response'a delay özelliği eklense çok daha güzel olabilir.

Hyanide2025年7月23日

Very nice and good

Best extension for network debugging

Rafael Escolar2025年7月22日

Perfect to debug using our dev env instead of live

Beer Gold2025年7月22日

requstly is really very useful, it greatly simplifies the threshold for debugging and packet capturing, and its hijacking capabilities are very outstanding.

Jannick Vandaele2025年7月21日

works perfect

M & FP2025年7月20日

This is good app for testing my program, it is easy to use and has plenty good features than other same function extensions that existed.

AI product read

Intercept, modify, and mock HTTP(S) network requests and responses directly in the Chrome browser

Enables web developers and QA engineers to modify network traffic (redirect URLs, modify headers, inject scripts, mock API responses) without setting up a proxy server, avoiding VPN issues and latency. Allows frontend development when backend APIs aren't ready, testing local JS/CSS changes on production sites, and overriding REST/GraphQL API responses.

User installs the extension, creates HTTP rules (redirect, headers, script injection, mock API responses) via the extension popup or the Requestly web app at app.requestly.io. Rules are stored locally in chrome.storage.local. When browsing, the service worker intercepts matching requests using declarativeNetRequest and webRequest APIs, applies the configured rules, and optionally records sessions for replay. The extension integrates with the Requestly web app for advanced rule management, team collaboration, and cloud sync.

Target users: Web developers / QA engineers / Frontend developers / DevOps engineers / API testers

Source code is heavily minified making detailed logic analysis difficult
Could not definitively determine if the web app UI (popup React app) requires login or renders locally without auth
The devtools/index.js is 1.69MB minified - deep inspection was not feasible within tool budget

Monetization

No paid features detected

No payment-related code found in the extension source: no premium/subscription/billing/pricing/upgrade/stripe keywords detected. The 'checkout' matches are all from the rrweb session recording library (checkoutEveryNms, isCheckout parameters) which is session replay checkpoint terminology, not payment. The extension is open source (https://github.com/requestly/requestly/). No feature gating, license checks, or payment UI found in the extension code. The destination service (Requestly/BrowserStack) likely has paid team/enterprise plans, but the extension itself does not gate features behind payment.

Confidence: 70
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension's core rule-application engine works locally without login (rules stored in chrome.storage.local). However, the extension heavily integrates with the Requestly web app at app.requestly.io for session recordings (SESSIONS_URL), rule management UI, team collaboration, and cloud sync. The app.cs.js content script injects on requestly domains to bridge the extension and web app. Session recording drafts open at app.requestly.io/sessions/draft/{id}, and the externally_connectable manifest connects to BrowserStack domains. Login to the destination service (Requestly web app) is required for the full workflow including cloud features, session replay, and team collaboration.
