Tamper Dev

Intercept and edit HTTP/HTTPS requests and responses as they happen without the need of a proxy.

What is Tamper Dev?

'Tamper Dev' is a Chrome extension designed for developers and pentesters to intercept and edit HTTP/HTTPS requests and responses in real-time. It functions without the need for a proxy or additional software. Now supporting multiple browsers, this tool allows you to filter and modify requests before they are sent to the server and responses before they return to the browser, simplifying debugging and vulnerability hunting.

Summary

Analyze keywords

If you are a developer, you can use Tamper Dev to debug your websites, or if you are a pentester, you can use it to search for security vulnerabilities by inspecting the HTTP traffic from your browser.

Unlike most other extensions, Tamper Dev allows you to intercept, inspect and modify the requests before they are sent to the server, and before they are sent back to the browser interactively, and without any additional installed software.

How to use?

Press [ Alt ⌥ ] + [ T ] or click on the extension button
Filter the requests you are interested in
Enable interception, and trigger a new request
Modify all requests before they are sent to the server
Modify the responses before they are sent back to the browser

Does not show requests generated by Javascript. So, it is more or less useless on modern web sites.

Mario Sedlak, 2024-03-26

I needed to modify the body of a POST request and tried 10+ extensions. None worked, or atleast were too complicated for me to figure out. This one works like a charm. Very intuitive. This will be going in my toolchest.
