About SightDiff

Your coding agent says done. SightDiff renders before/after proof of every page and state of your app, locally, pre-commit, in one scannable sheet. Changed surfaces flagged, untouched ones verified identical. 66% of developers say their top frustration is AI code that's almost right, but not quite. The agent was asked to change one page, the proof sheet caught it changing two. A running dev server and a tiny config listing the pages and states you care about, SightDiff can even write that config for you by crawling your app.

We handle the full production stack, not just one piece. You stay in the parts that need your taste; we handle the rest. It writes the script first, then builds every visual around the story. You shouldn't also have to learn Premiere, hire a voice actor, design title cards, color-grade, and re-export six aspect ratios, just to publish what you already finished.
