As answered by people managing Tickvio and Cert Decoder.
Tickvio's answer
Tickvio was born out of frustration. While running email campaigns, I kept hitting the same wall: adding a simple countdown timer to an email shouldn't require a developer, shouldn't cost a fortune, and shouldn't leave you blind on performance data.
The existing tools were either overpriced for what they offered, painful to set up, or gave you absolutely no analytics after embedding. I wanted something that just works — design a timer visually, copy one URL, paste it anywhere, and actually see how it performs.
So I built Tickvio as a solo founder. The goal from day one was to make the simplest, most capable countdown timer tool on the market — with a free tier generous enough that most users never need to pay, and built-in analytics that no competitor was offering. No unnecessary complexity, no bloated feature set. Just urgency that works, everywhere.

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
Tickvio's answer

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.

Tickvio's answer
Most countdown timer tools either give you a clunky setup process, charge premium prices for basic features, or leave you with zero data after you paste the embed. Tickvio does things differently:

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
