A powerful Chrome extension that captures DOM snapshots at any point in time and performs detailed structural comparisons. Debug regressions after deployment, document changes for bug reports, and ensure visual consistency across releases.
Tracking DOM changes across deployments is tedious and error-prone without the right tools.
DOM changes after deployment go unnoticed until users report visual bugs. Manual checking is unreliable.
Comparing DOM structure before and after changes requires tedious manual inspection through DevTools.
Without snapshots, there is no way to see exactly what changed in the DOM between two points in time.
DOM Snapshot & Diff captures, compares, and visualizes DOM changes so you never miss a regression.
Capture the complete DOM structure in one click. Scope to specific selectors for focused analysis.
Side-by-side tree comparison with added, removed, and changed nodes highlighted in distinct colors.
See DOM changes highlighted directly on the live page with color-coded overlays for immediate context.
Everything you need to capture, compare, and debug DOM changes.
Capture complete DOM structure at any point with one click. Scope to specific CSS selectors for focused snapshots.
Side-by-side comparison with added, removed, and changed nodes highlighted in color. Up to 10 free diffs per day.
See DOM changes highlighted directly on the live page with color-coded overlays for immediate visual context.
Filter out irrelevant changes from ads, analytics scripts, CSRF tokens, and dynamic content. Focus on what matters.
Export diffs as HTML, JSON, Markdown, or PDF. Share clear, annotated reports with your team.
All snapshots are encrypted with AES-256-GCM and stored locally on your machine. Your DOM data is never transmitted to any server.
