What separates them is not the price. It is how many domains you can point it at, and whether it keeps watching them once you close the tab.
FreeAlways. Nothing to cancel.
One-off checks
Small jobs, done once. Open a tool, paste a URL, read the answer, close the tab.
FreeLimited time, while it is in early access.
One site, watched
For the person who owns the site. Claim it once and let it re-audit itself on a timer.
FreeLimited time, for the first accounts on it.
Every client site
For someone who answers for a shelf of sites, not one. Write in and it is switched on for your account.
Every figure here is a limit the code enforces, not a target. Pick a plan to follow its column down the table.

None that is hidden. The tools are new and billing is not built, so the limits do the rationing instead of a card. If a plan ever starts costing money, account holders are told by email before it does, and nothing is charged without you agreeing to it.
Not for a one-off. Every tool and the site audit run signed out. An account is what keeps your history and lets a site re-audit itself on a schedule.
A bare hostname. example.com and www.example.com are the same domain; shop.example.com is a different one. Claiming proves nothing about ownership, which is why a claim buys a small recurring crawl rather than a large one — and why it grants no exclusivity. Several accounts can hold the same domain and see the same history, so an agency and its client are not left arguing about who claimed it first.
Yes, where the client has asked you to. Crawl only sites you own or have permission to test — that is a condition of the terms, not a suggestion.
Ask, and the Agency plan is switched on for your account. It is granted by hand rather than by a button because nothing here verifies that a domain is yours, and an unverified account with a fleet of recurring crawls is a crawler for hire. The crawl limits stay the same either way — a plan buys more domains, never a heavier crawl of any one of them.
Delete the account and the audits go with it. Release the domain instead and it returns to the pool, with the history left on the record for whoever claims it next.
No account, no card. Claim a domain later if you want the site watched.
