As answered by people managing DNSimple 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:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

I should add a friend has recommended DNsimple.com and I’ve previously found their service to be excellent. https://dnsimple.com/ 50 cents per domain per month. - Source: Hacker News / 5 months ago
If you’re still looking for an alternative, https://dnsimple.com is an excellent engineer focused no bullshit domain registrar and they support .co.za. - Source: Hacker News / over 2 years ago
I also use and love the service provided by https://dnsimple.com/. Source: over 3 years ago
Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
