Compare 2–5 URLs side by side with a structured diff.

Returns each URL's score + category breakdown plus a diff object that tells you who is ahead and by how much, per category, per URL pair. Built for agencies who embed comparisons in sales decks and for devs who want a one-call sanity check across an old vs. new deploy.

Send JSON: {"urls": ["https://a.com", "https://b.com", ...]} Requires Basic plan ($15/mo) or higher.
