AI 产品解读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.

- 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

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.

- 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.
Удобный и быстрый сервис. По сравнению с другими аналогами - лучшее решение!
It is a combination of charles and postman and the good UI along with the ease of setting up multiple rules really enhances productivity
I am a Frontend Developer who used to write and debug JavaScript code. I am in deep love with this Requestly App it help me so much during my daily work.
Really helpful for workflow.
it does what it says and does it perfectly

Requestly is not just one of the best — it’s the best HTTP interceptor for network calls that I’ve found. It’s incredibly helpful for testing purposes: modifying API responses, redirecting requests, and simulating different scenarios is simple and reliable. Great job!
Requestly is an exceptionally useful API and network debugging tool that significantly improves developer productivity. Its ability to intercept, modify, redirect, and mock API requests in real time makes it an essential companion for frontend and full‑stack development. What stands out most is the ease of use. The interface is clean, intuitive, and well-organized, allowing even first-time users to start creating rules and mocking APIs with minimal learning curve. Features like request/response modification, API mocking, HTTP header manipulation, and endpoint redirection are incredibly helpful for testing edge cases, debugging issues, and working independently of backend readiness. Requestly also excels in team collaboration. Shared rules and environments make it easier to maintain consistency across development and QA teams. This is especially valuable in fast-paced agile environments where backend APIs frequently change. Performance-wise, the app is lightweight and reliable, with minimal impact on browser performance. The browser extension integrates smoothly with Chrome and other Chromium-based browsers, and the desktop app adds flexibility for more advanced use cases. Overall, Requestly is a powerful, well-thought-out tool that saves time, reduces dependencies, and streamlines API testing and debugging. It’s highly recommended for developers, QA engineers, and anyone dealing with APIs on a regular basis.
very helpful tool
As a QA, this tool helps me greatly in mocking API response without touching much in code base
