Browser Screenshot Diff

Compare two recorded sessions step-by-step. Pairs each step in session A to the same step-id in session B, diffs the captured screenshot and accessibility snapshot, reports the first divergence and an aggregate similarity score.

When to use

• Visual regression after a UI change (record before, record after, diff).
• Verifying a browser-replay run matches the parent session within tolerance.
• Comparing two A/B variants of the same form flow.
