As answered by people managing Cert Decoder and Storelister.
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
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Storelister's answer:
Dropshippers and Shopify store owners doing product research. That includes people just starting out who need to find their first niche, and experienced sellers who want to stay current on what's moving in their market. E-commerce consultants and agencies also use it to research categories on behalf of clients.
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.
Storelister's answer:
The data comes directly from live Shopify stores. Products are organized by niche so you can research any category in seconds instead of visiting stores one by one. Finder gives you a way to discover products you'd never think to search for, including digital products. And there are no feature tiers. Every subscriber gets full access to everything, every niche, every filter, every tool.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Storelister's answer:
StoreLister tracks Shopify stores the day they launch and organizes their full product catalogs into 225+ niche categories using AI. Most research tools pull from ads or social media. StoreLister pulls from actual store shelves. That means you're seeing what sellers are betting their own money on, not what's going viral. The database updates daily, and Finder adds a swipe-based discovery layer that no other product research tool offers.

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
