The Punisher vs. Percy

Both tools help teams ship better-looking software, but they answer different questions. Percy asks "did this page change since last time?" The Punisher asks "does this page match the Figma design?" Understanding that distinction is the fastest way to pick the right tool — or to use both.

When Percy is the right choice

Percy shines when you have an established UI and want to guard it against unintended change. Its snapshot-and-baseline model integrates into CI and flags any pixel that moved between two builds. If your main risk is "a refactor silently broke a page that used to be fine," that's exactly what it's built for.

When The Punisher is the right choice

The Punisher is built for the other half of the problem: making sure the implementation matches the design in the first place. Because it uses your Figma file as the reference, it works on brand-new pages with no history, and every difference it reports comes with the exact values to change — ready to paste into GitHub Copilot, Cursor or Claude.

Use them together

Many teams run both: The Punisher verifies a page matches Figma at build time, and snapshot visual regression testing guards it against future drift. One anchors to design intent; the other anchors to the last known good state.
