Requestly has been a great asset for instantly creating client demos. I love their script injection feature which allows me to inject our code into any website and really impress our clients as they see our product on their website during demos :). It's probably one of the best developer extensions out there. Great job Sachin and the team! 👏👏

This is by far the best tool for managing request headers! Plus the developers are very active meaning you'll get help if you're ever stuck or need help solving a problem. I use it daily and couldn't be happier.

Lucas Laricchia2023年7月4日

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.
