General
Is the website checker really free?
Yes. The website checker and the free tools work without an account. Limits only stop automated abuse.
Do I need to be technical to use this?
No. Type your website address and read the results. Anything that needs fixing comes with a plain explanation and a guide.
Will checking my site change anything on it?
No. We only read public information, the same way a visitor’s browser or an email server would.
Website checker
Can I check a website that isn’t mine?
Yes. Everything in the report is public information that any browser or mail server can already see.
How do I check when my SSL certificate expires?
Run a check on your domain. The security section shows the expiry date, the issuer and whether the certificate chain is complete.
Why do my emails go to spam?
Most of the time a missing or broken SPF, DKIM or DMARC record is to blame. The email section of the report shows which one needs attention.
What is a DKIM selector and where do I find it?
It is the name your email provider gives your DKIM key, such as “google” or “selector1”. Your provider’s DNS setup page lists it.
Free tools
Do the browser tools send my data anywhere?
No. Tools like the password generator, Base64 and the JWT decoder run entirely in your browser. Only checks that need a server, like DNS or ping, go to ours.
