redirect.pizza automatically installs an SSL certificate on your domain. This means that redirects with "http://" & "https://" are both working.
On top of this, we make sure the SSL ciphers are up-to-date. Only the most secure TLS versions are supported and we'll automatically renew the certificate before it expires.
We're build on top of the SSL giants of LetsEncrypt & ZeroSSL and can't offer redirect.pizza without them.
Why use 2 issuers? Redundancy! When one of those isn't responding or is rate limited, we can automatically fallback on the second one.
We're proud to have an A+ rating from Qualys SSL Labs for our HTTPS redirects in all the different plans, even Free!
