Capture screenshots of any site — single URL, sitemap, or CSV — and diff them between runs. Catches visual regressions your test suite can't see, before your users do. Full-page or sectioned, light/dark mode, authenticated pages, CI-ready exit codes. Open source, MIT licensed.
Built this because I needed to screenshot client sites before handoffs, doing it manually for over a year before packaging it up properly. It's part of NFSFU234 Open Source Day today — two other tools of mine (TourGuide, FormValidation) are also getting their biggest updates yet, all now under one npm scope. Happy to answer anything about how it works or what's next.
