Tamper Dev

Tamper Dev

Allows you to intercept and edit HTTP/HTTPS requests and responses.

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.

How to use Tamper Dev?
1/ Press [ Alt ⌥ ] + [ T ] or click on the extension button
2/ Filter the requests you are interested in
3/ Enable interception, and trigger a new request
4/ Modify all requests before they are sent to the server
5/ Modify the responses before they are sent back to the browser
