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?

  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
