Questions & Answers

What's the story behind your product?

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.

OfferStack's answer:

OfferStack was created to solve a common problem in WooCommerce stores: managing promotions often requires multiple plugins with different interfaces and limitations.

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
