As answered by people managing Contestit and Cert Decoder.
Contestit's answer
I was tired of seeing the same like, follow, retweet, giveaways and wanted to make something different.
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
Contestit's answer
The primary audience for Contestit is social media creators and businesses looking to host a giveaway.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Contestit's answer
You should choose Contestit over the other competitors because of it's unique game features that let users play games to get more entries and increase engagement.
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.

Tracking Contestit since Oct 2025.
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
