Compare two Lottie animations side-by-side

Load two Lottie files and play them in lockstep with a shared playhead. Compare mode is built for checking an optimized export against the original, reviewing animation revisions, or QA-ing a recolor, all without flipping between tabs.

Synchronized playhead: both animations scrub and play together
Side-by-side canvases so differences are obvious at a glance
Drop any two .json or .lottie files, nothing is uploaded
100% client-side: your files never leave the browser
