Code Verify

Code Verify is an extension for verifying the integrity of a web page.

The idea is you can publish what JavaScript/CSS should appear on your site into a "manifest". The manifest consists of the hashes of all the JavaScript/CSS files in a given release. This browser extension can consume the manifest and verify that only that code executes, or else display a warning to the user.

Installation

You can install Code Verify from the extension store of Chrome, Firefox, Edge, or Safari.
