Wraith is super useful for web development on existing complex sites and I rarely hear of it or existing tools. Setup a staging site along with your production site, list the important URLs and when you run Wraith it'll compare screenshots of changes between the URLs on staging and production. This lets you update existing pages and verify you've not broken other pages with only a small amount of setup. See https://github.com/BBC-News/wraith https://github.com/BBC-News/wraith
