CrawlProof

Free · No signup · Up to 50 pages

Find the careless mistakes on your site.

The Slop Score sweeps up to 50 pages and reports what is observably broken or sloppy — placeholder copy that shipped, template variables that never resolved, staging URLs in live links, duplicate pages, stale dates, missing alt text. One score, and a per-page list of what to fix.

Scan type

No email, no signup, no card. The report opens on-page in seconds — you can email yourself a PDF copy from the report once it's ready.

Three visibility levels: Public (checked above — shown on Recent scans and indexable), Unlisted (default — reachable only by its report link, never listed), and Private (sign up and save the URL as a project to keep scans in private history). Common tracking parameters are stripped before the URL is saved.

Runs no AI model, so there is nothing to queue behind and nothing to pay for. The report opens on-page in seconds and is yours to share.

How the score reads

The dial runs the opposite way to a grade: 0 is pristine, 100 is maximum slop. Lower is better.

0–25 · Clean

Nothing obviously careless. Fix the stragglers and move on.

26–50 · Careless

Real defects a visitor can hit. Usually a handful of pages doing most of the damage.

51–100 · Sloppy

Systemic — the same mistake repeated across templates rather than one bad page.

What gets swept

Content

Filler and placeholder copy, thin pages, near-duplicate pages, stale dates, claims with no evidence behind them.

Code

Leaked template variables, preview-host URLs pointing at staging, dead links, broken or missing resources.

Design

Missing viewport, missing alt text, layout-shift risks, palette and type sprawl across pages.

The kind of thing it catches

Every finding points at a specific page and a specific line of evidence — never a vibe.

“Coming soon” shipped to production

A standalone element still reading as a placeholder, months after launch — on a page that is linked from your nav.

Leaked template variable

A literal {{product_name}} or [insert company] rendered to visitors because a merge field never resolved.

Preview host in a live link

A production page linking to your-app.vercel.app — the staging copy, indexed and reachable.

Near-duplicate pages

Six location pages that differ only by the city name, splitting their own ranking signal.

What this is not

This is not an AI-detector. We never estimate whether a human or a model wrote your page, and we never report a probability that it did. Those classifiers cannot be checked against the truth, and they misfire hardest on people writing in a second language.

Every Slop Score finding is an observable defect — something you can open the page and see for yourself. If you disagree with one, you can prove us wrong, which is the whole point.
