Live Preview & Diff

See the app and the file changes before you merge

Live Preview gives you a URL early; diffs keep edits reviewable - together they shorten the “does it actually work?” loop.

  • Preview URL from early iterations
  • Line-by-line diff beside the thread
  • Fits normal PR and CI flow

Live Preview & Diff

From edits to confident review with less guesswork

Use Preview + Diff when UI behavior is hard to infer from code alone - especially layout, flows, and regressions.

  • Open a live preview URL without a bespoke deploy pipeline
  • Review changes line-by-line next to the conversation
  • Catch visual regressions before merge
  • Shorten review cycles on frontend-heavy work
  • Still route through your normal PR and CI gates
