As answered by people managing Toucan 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.

Very clever. Toucan [1] does something similar (but I think only at a word level, not sentences), so might be worth looking at what they do in terms of marketing. [1] https://jointoucan.com/. - Source: Hacker News / almost 2 years ago
This is great but not sure about the price. It upkeep so high for this to justify the cost ? https://jointoucan.com/ does the same but is free. - Source: Hacker News / almost 2 years ago
This looks nice and similar to toucan [1]. I have built something similar but a bit different for the web [2]. Happy, to share the code in a non-so-permissive license with you if you plan to build out web support. [1]... - Source: Hacker News / over 2 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
