Requestly is an excellent tool with outstanding support and a user-friendly interface. It's highly intuitive, making it easy to modify, block, or redirect requests. Perfect for developers and testers who need reliable, flexible request control options. Highly recommended!

Ziii2024年11月2日

you need to pay monthly fee at least $8 just to redirect links to another website 🤣🤣🤣🤣

Rajat Tyagi2024年10月23日

Requestly is an invaluable tool that helps us test, validate, and troubleshoot our features and client integrations.

Isa Krasniqi2024年9月25日

If you are back-end and you need to see how the front would look with without bothering them, it is perfect tool ,also the support team is very quick and accurate.

Fikret Hassan2024年9月19日

An essential tool for any frontend developer. I would be far less efficient if it did not exist and not only that, their level of support is stellar and they're always improving and adding more features too!

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.
