frida-interception-and-unpinning VS Requestly

I recently used Fiddler along with Frida[1] to deal with cert pinning in the app I was looking into.

If you want to intercept and modify a incoming json response for some specific url pattern, would a service worker be a good way to do so?

To illustrate, assume I frequently browse example.com and want to trick my browser into thinking that I have "favorited" every post. It's trivial to write a for loop that iterates over response.json and sets `is_favorite = true`. But it's not as clear to me where this script should ideally live in order to have the logic always executed before the response is made available to the site.

Your comment made me think about whether I can replace my overkill solution (https://requestly.io/) with something lightweight.

If you prefer open-source there is Requestly and Toolkit.

If you don't know Requestly, It is an open-source Chrome/Firefox/Edge extension to intercept & modify HTTP requests & responses. One of the popular features is to modify HTTP headers. We also offer workspaces for easy collaboration between team members.

Hey, open-source community, This is Sachin, One of the core maintainers of Requestly - An open-source alternative to Charles Proxy & Telerik Fiddler. In case you don’t know about Charles Proxy & Fiddler, both of them are two decades-old products used widely to Inspect & Modify HTTP traffic in web & mobile apps.

In /etc/hosts file you put only IP addresses and hostnames, i.e. 127.0.0.1 cdn.cloudflare.steamstatic.com. Then you have to set up a web server on localhost port 80 and put your image at http://localhost/steamcommunity/public/images/apps/753/1d0167575d746dadea7706685c0f3c01c8aeb6d8.jpg as well as other files from https://cdn.cloudflare.steamstatic.com. You also have to keep the URLs updated when they change upstream. It's not worth it. Better use a local proxy server like mitmproxy or requestly.

Requestly founder here. You are essentially looking for Requestly - A Chrome/Firefox browser extension to Intercept & Modify HTTP requests. Using Requestly you can actually do the following things

For development/Debugging: 1. VSCode - Got used to the key bindings and integrated terminal, so now it's really hard to switch 2. Requestly - For easily setting up local debugging environments. I am less of a UI guy, so this allows me to use the live UI of a deployed site, and redirect whichever request I want to play with to my local server. 3. Wireshark - To better understand a network protocol.
