One engine, every tier
Anonymous scans provide a fast public-site check. Signed-in scans run the deep engine; your plan controls page depth, report detail, and repeat workflow. Upgrading reveals the evidence already collected for your signed-in reports.

🔁
Your site changes. The tells change with it.
One developer push, one swapped template, one new page, and a clean grade can quietly slip. Rescan after changes and catch it before a customer does.
🧬
The builders keep evolving.
Lovable, Bolt, v0, and Cursor ship new patterns every week. We keep teaching SiteBlob the new ones, so a scan from three months ago already knows less than a scan today.
📈
Best used on repeat.
Treat it like a recurring check, not a one off. It is the quiet alarm that keeps your site from looking rushed to people who have never met you.
SiteBlob does not prove how a site was built. It flags visible signals that can make a site feel generic, rushed, AI assisted, or less trustworthy.
Launch pricing: early subscribers get $19/mo (normally $29/mo) and keep that rate until they cancel. See refunds and terms.
