Buy monthly credits for deeper scans and recurring checks.
Free user credits reset separately each month.
What you are buying, and what happens when a limit runs out.
Fetching a page costs one credit, and so does checking each link, image, script, stylesheet or media file found on it. Pricing therefore tracks the real work of scanning rather than a page count, and a link-heavy site consumes more than a sparse one of the same size.
The domain limit is how many distinct sites you can scan in a billing month, and the concurrency limit is how many scans may run at the same time. Higher plans raise both, which matters most if you manage several sites and want them rechecked on a schedule.
Guests can scan without an account under daily limits. Registered users get a separate monthly free allowance that resets each month, and a paid plan adds its credits on top of that. Free credits are not consumed before paid ones are exhausted.
A scan that reaches your limit pauses rather than discarding what it already found, so the issues discovered up to that point stay in the report. Adding credits lets the same scan continue instead of starting over.
Finished reports stay available for a fixed period that depends on your plan, after which they are removed automatically. Export anything you need to keep long term as CSV, which paid and registered accounts can do from any finished scan.
Plans are billed monthly in US dollars and paid by cryptocurrency through our payment provider. Payments are final and non-refundable except where applicable law requires otherwise. Use a guest scan or free credits to test the scanner on your own site before buying.
