The web scan is free and needs no account.
For sites built with Lovable, v0, Bolt, Replit, Cursor, Claude Code or Codex
AI builders reach for the same blue, the same font and the same three cards, so their sites end up looking alike. Paste your URL: Sailop finds every default left on the page and writes the fix, ready to hand to your coding agent.

What a result looks like
Each cell is one of the eight signatures, sized by its weight in the score. A filled cell was found on the page. It steps through 3 real scans from 13 October 2026: tailwindcss.com (7 of 8), flowbite.com (4 of 8) and stripe.com (1 of 8).

Sailop does not judge taste and does not guess who wrote the page. It fetches the HTML and up to six stylesheets, then looks for eight things a generator leaves in place when nobody changes them.
A signature is a default, not a verdict. On 13 October 2026 the same test found one on stripe.com and two on linear.app.
Why bother: people form an opinion of how a page looks in about 50 ms (Lindgaard et al., 2006), and in a Stanford study of over 2,500 people judging whether to believe a site, 46% of their comments were about its look (Fogg et al., 2003).
Site report
Defaults rarely sit on one page: they live in the shared header, the card component, the theme. The site report checks up to 25 pages, shows where each default turns up, and writes the prompt that fixes it at the source.

Next: the Sailop CLI
The Sailop CLI reads source files instead of rendered pages, and can fail a CI run when a default comes back. It is built and not published on npm yet.
Get one email when it ships
Eight signatures on one rendered page: the default blue family, the blue to purple gradient, Inter or Geist as the page font, the three-card row, fade-up on scroll, repeated frosted glass, stock button copy and soft shadow cards. Each one found comes with the token it matched and a count.
Anyone who shipped a page with Lovable, v0, Bolt, Replit, Cursor, Claude Code or Codex, or a starter template and wants it to stop looking like every other one: developers, indie founders, and studios checking a page before or after a client sees it.
No. It means a default was left in place. People ship these too, and plenty of generated pages carry none. The count tells you how much of the page is still the starting template.
A design system seeded from your hostname (palette, type pair, spacing, radius), the literal class swaps that move your markup onto it, a Tailwind v4 theme, plain CSS variables, font tags, and an agent brief for Claude Code, Codex, Cursor or GitHub Copilot.
Because it is generated from the hostname, with no model call. Same domain, same system. Another domain gets another one.
Anything outside the page it fetched. It reads the HTML and up to six linked stylesheets of one URL. On a Tailwind site most classes live in compiled CSS, so the markup count is the part you can change by hand. The CLI reads source files instead, and it is not published yet.
From a URL scan, nothing: the page is fetched, checked and answered, and neither the page nor the result is stored. Visits are counted without cookies.
The one-page scan and its fix kit are free, with no account. The site report (up to 25 pages, a fix prompt per default) has a free preview; the full report costs 19 EUR once, by card, refund within 14 days. Pro, the paid tier of the CLI, is planned at 49 EUR once and is not on sale until the CLI is published.
The same eight checks run on up to 25 pages of your site, from its sitemap. It shows which default sits on which page, and writes one prompt per default for Claude Code, Codex, Cursor, GitHub Copilot, Lovable, v0, Bolt or Replit that names those pages and the classes to change. The preview is free.
There is no date to give yet, so we are not giving one. Leave your email in the launch list on this page and you get one message on the day it can be installed.
