TraceUI helps developers catch visual bugs in web applications before they reach users.
Developers can upload before-and-after screenshots from a code change, and TraceUI compares them, highlights changed UI regions, creates a diff mask, and classifies the change as likely bug, expected change, needs review, or no meaningful change. It also gives practical debugging suggestions so developers know where to inspect next.
For the deeper investigation flow, TraceUI goes beyond pixel comparison. It localizes the changed region, maps it back to the affected DOM element, compares computed styles, uses Meta SAM 3.1 for visual segmentation, and uses Muse Spark to produce an evidence-backed root-cause explanation and recommended fix. The demo catches a broken Add to Cart button, identifies the CSS override that caused it, and verifies the corrected version with 13/13 checks passing.
The goal is to make visual testing less manual for solo developers and small teams without dedicated QA.
