Compare Chrome extensions: Tamper Chrome (extension) vs WA Self Sender - Free Messages Sender

NOTE: There is a new version of this extension called Tamper DEV - install at https://tamper.dev. Tamper Chrome will continue to work but it's suggested you move to tamper.dev for a better experience.

To use it, refresh the website and look at the developer tools (left-click -> inspect element). Tamper Chrome will appear in a new tab. See the tutorial here: https://github.com/google/tamperchrome/blob/master/README.md

Tamper Chrome allows you to monitor requests sent by your browser and the responses. You can also modify requests as they go out, and to a limited extent modify the responses (headers, css, javascript or XMLHttpRequest responseText).

See what websites are sending in the background, modify submissions, switch out scripts, alter AJAX responses, Tamper Chrome puts the power of your browser back in your hands.

Tamper Chrome will prompt you to install its companion application when you first run it.
