Overview

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

Bringing back the good old tamper.dev plugin from Google which is currently unusable as it has not been maintained for about 5 years now. Fully upgraded and works with a minimal set of features that meets the MVP standard and conforms to Manifest V3. Enjoy and feel free to open support requests for updates! Stay tuned for more updates like Hex Editor in the future! Intercept and edit HTTP/HTTPS requests and responses as they happen without the need of a proxy. 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
