As answered by people managing Retrnly and Cert Decoder.
Retrnly's answer
Retrnly was created to solve a common ecommerce problem: return reasons, reviews, and support complaints are often stored in separate systems and reviewed manually. Retrnly brings this information together and turns it into a practical product-improvement plan.
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
Retrnly's answer
Retrnly is built for ecommerce founders, product managers, operations teams, and customer-experience teams. It is most useful for stores with enough return and customer-feedback data to identify recurring problems across products.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Retrnly's answer
Retrnly is designed for teams that want to prevent future returns, rather than only process refunds and exchanges. It works alongside an existing returns workflow and provides product-level risks, recurring feedback themes, prioritized recommendations, and estimated savings opportunities.
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.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Retrnly's answer
Retrnly combines return reasons, customer reviews, support tickets, and product data in one analysis. It identifies the causes behind recurring returns and recommends specific product, sizing, listing, expectation, and quality fixes. It also estimates the potential savings from reducing avoidable returns.

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
