WebRynx

See token drift, not just changed lines.

Compare CSS custom properties or DTCG JSON. Trace aliases, broken references, final values and exact replacement candidates.

CSS and DTCG JSON 3 MiB per file Every migration needs review

Choose two token snapshots

Compare like with like: CSS to CSS, or DTCG JSON to DTCG JSON.

Choose one before file and one after file.

Analysis boundaries
  • CSS declarations are compared as authored tokens, not through the full browser cascade.
  • DTCG groups inherit $type and token objects require $value.
  • Missing aliases and reference cycles are reported without infinite traversal.
  • Exact replacement candidates match both resolved value and effective type.

Selected token content is processed in this page and is not sent to a WebRynx application endpoint.
