As answered by people managing Robomonkey and Cert Decoder.
Robomonkey's answer
Both founders had a chance at building Chrome extensions in the past and were frustrated by the complexity of the whole process.
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.
Robomonkey's answer
We use the most recent AI models for the coding agent, the extension itself, and our server-side code are written in the latest Typescript standard.
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

Robomonkey allows anyone to build browser extensions without programming knowledge
Cert Decoder's answer:

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
