As answered by people managing Cert Decoder and Kazkar.
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.
Kazkar's answer:
Meet us here - https://kazkar.com/about
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.
Kazkar's answer:
Two audiences, one platform: For Children (ages 3–12) Kids who want to see their own hero — an animal, creature, or character they created — come alive in a new story every single day, with music made just for them. For the Adults Who Choose the Platform
Parents looking for screen time that's imaginative, safe, and calming at bedtime — not passive consumption Teachers and early years educators who need ready-made, curriculum-adjacent storytelling content that engages reluctant readers and supports emotional literacy Schools and nurseries seeking an off-the-shelf EdTech tool that covers stories, music, feelings, and life skills without requiring lesson prep
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.
Kazkar's answer:
Kazkar gives you: A hero that's yours — built once, lives in every story forever A new adventure every day — no repeats, no stale content Original music — not background noise, but songs and soundscapes written around your child's story A birthday song and invitation — personal enough to print and hand out Audio theatre — full cast, multiple voices, like a radio drama made just for your child
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Kazkar's answer:
Every other platform stops at illustrated text or basic narration. Kazkar generates a personalised story and an original soundtrack together — lullabies, genre remakes, audio theatre with character voices, and ambient soundscapes — all starring a hero the child actually owns. Family owned.

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
