Code Verify is an extension for verifying the integrity of a web page.
The idea is you can publish what JavaScript should appear on your site into a "manifest". The manifest consists of the hashes of all the JavaScript 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.
You can install Code Verify from the extension store of Chrome, Firefox, or Edge. (Safari support coming soon, also direct links to the extensions.)
