How the free tools work
- Every tool gives five free checks of five domains each, no account needed.
- When the free checks are used up, sign up: you get a trial budget and can check without limits.
- The tools use open sources only, so the results are free for you and for us: no paid metrics, no caps on what you see.
- A short captcha before every check keeps scripts out.
