A Chrome extension that uses recheck-web to let you manually create 'checkpoints' of web sites. Using recheck-web together with the recheck.cli or the review GUI, you can now easily find differences in websites. Using filters, you can easily differentiate between style, positioning or content differences—-you can even define your own category!
Find the recheck-web extension in the Chrome Webstore and click install.
Please report any bugs that you find as issues on the project.
