As answered by people managing RSS3 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 started to use Follow [0][1], which uses RSSHub [2] and RSS3 [3] in addition to classic RSS. [0]: https://follow.is/ [1]: https://github.com/RSSNext/follow [3]: https://rss3.io/. - Source: Hacker News / almost 2 years ago
The RSS3 website(rss3.io) itself is powered by the same API. Type in any ENS and try it out. Source: almost 4 years ago
Here I want to share a method that is free and platformless, combing RSS3.io , a web3 RSS subscription service, and NFT whale ENS information from NFTGO: https://nftgo.io/whale-tracking/list. Source: about 4 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
