Questions & Answers

As answered by people managing Cert Decoder and Cardixx.

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.

Cardixx's answer:

We built Cardixx after seeing paper business cards get thrown away and existing apps fail to foster real-world connections. We built a tool that turns physical encounters and workspace check-ins into structured digital relationships.

Which are the primary technologies used for building your product?

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

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Cardixx's answer:

Modern professionals, startup founders, freelancers, sales representatives, digital nomads, and event organizers who network face-to-face and work in shared spaces.

Why should a person choose your product over its competitors?

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.

Cardixx's answer:

Competitors only replace paper business cards. Cardixx links digital contact sharing with physical locations, allowing users to check into events, locate productive workspaces, and exchange verified profiles using dynamic QR codes.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Cardixx's answer:

Independent Freelancers & Consultants across the DACH Region Coworking Hubs & Shared Office Spaces in Vienna, Berlin and Turkey Tech Startup Founders & Regional Event Organizers

What makes your product unique?

Cardixx's answer:

Cardixx combines digital business cards, real-world venue check-ins, and coworking space discovery into a single iOS and Android app. Instead of just sharing static contact details, users find and connect with nearby professionals based on physical locations and shared work hubs.

    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
