Questions & Answers

As answered by people managing Wallper and Cert Decoder.

What's the story behind your product?

Wallper's answer

Wallper started as a weekend project. After switching from Windows, we couldn’t believe how limited macOS was when it came to live wallpapers — there just wasn’t a clean, native solution like Wallpaper Engine. We built the first version just for ourselves, to bring our desktops to life again. But as we shared it with friends and online communities, it quickly turned into something much bigger. What began as a personal fix is now a fully featured app used by thousands of Mac users around the world.

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.

Which are the primary technologies used for building your product?

Wallper's answer

Wallper is built entirely in Swift & SwiftUI. Everything is optimized for macOS with no Electron or cross-platform layers.

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?

Wallper's answer

Mac users who care about aesthetics, productivity, and simplicity. Creatives, developers, designers - anyone who wants their desktop to feel alive and personal.

Cert Decoder's answer:

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

Why should a person choose your product over its competitors?

Wallper's answer

Most alternatives are either outdated, heavy on resources, or require a login. Wallper is fast, lightweight, fully local, and respects your privacy. Plus, it’s designed specifically for macOS.

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.

Who are some of the biggest customers of your product?

Wallper's answer

Used by teams at indie studios and design agencies

Cert Decoder's answer:

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

What makes your product unique?

    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
