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

About Tamper Dev:
This is the new version of the extension previously called Tamper Chrome, but now supports multiple browsers, and does not require an auxiliary app. This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy Interceptor, but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install).
Thanks to the author, it’s very easy to use and i like the design!
Works as advertised. Can’t ask for much more.
Failed to attach to xxx – probably because of enterprise policies.
what?
There is no way to just intercept ONE request or intercept filtered request… it just intercept everything. In addition, I tried to intercept the production js file and replace it with a development version, but the file itself is quite large, so when you try to copy paste it into the response body, the whole thing freeze for a whole minute. The UI needs work too.
I wanna say author – Thanks! Really cool extension with friendly UI and very useful functional. But you can do this app better, if you add supporting Cyrillic charset it will be awesome
very good app. good interface works well and overall a good app.
