As answered by people managing No-IP and Cert Decoder.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Cert Decoder's answer:

First: static public IP is not necessary for selfhosting small services. The reason you want static ip is because when you have dynamic dns, it takes time for the DNS records to update when your IP changes. It makes sense to have static... Source: about 3 years ago
