As answered by people managing Twork App and Cert Decoder.
Twork App's answer
I was sitting in a cafe with a friend, working. We had this idea, and over the next few days, I started programming a prototype. Now the app has been released and is growing and getting better by the day.
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.
Twork App's answer
For the app, I use Flutter, and for the backend Laravel.
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
Twork App's answer
Digital nomads, business travellers, developers, entrepreneurs.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Twork App's answer
Users use the Twork app instead of a website. More flexible and faster on the move.
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.

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
