Requestly is one of the most valuable extension. It greatly helps in testing changes with large data and thereby reduces risk of unexpected API data.

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.
