About WebPeeks

What this site is

Free browser tools for checking a website's headers, certificate, DNS, redirects and metadata.

How the tools work

Every tool runs entirely in your browser. There is no account, no server-side processing and nothing you enter is transmitted or stored. Where a tool uses a formula or a data source, the page says which one and where it stops being reliable.

Corrections

If something here is wrong, please say so. The methods are stated on each page so they can be checked.
