  "summary": "DiffLens is a web app designed to compare local and staging web applications visually, content-wise, and markup-wise. It addresses the issue of manual checks missing small changes such as layout shifts, altered text, and unexpected DOM updates. The tool captures both pages using Chromium at a fixed 1920 × 1080 viewport and compares them using pixelmatch for visual differences, line-by-line text comparison for content differences, and element snapshots matched by rendered CSS path for markup differences. DiffLens provides separate comparison layers for visual, content, and markup changes, enabling developers to understand the differences and ship with confidence.",
