Questions & Answers

As answered by people managing StealthPeek and Cert Decoder.

What's the story behind your product?

StealthPeek's answer

A small team with a background in privacy and data kept running into viewers that demanded a login or faked their results, and the honest option was missing. So we built one: public content only, no credentials, no tricks.

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?

StealthPeek's answer

Next.js and React on the front end, backed by our own fetching infrastructure that pulls public content so your identity stays out of the request.

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?

StealthPeek's answer

Professionals who need to see public Instagram content without being seen: marketers checking competitors, journalists verifying posts, recruiters reviewing profiles. At home, partners and parents checking what loved ones share publicly. The common thread is wanting to browse without leaving a trace.

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?

StealthPeek's answer

No account or login, so your name never appears in a seen list. Downloads come out in original quality with no watermark. And we keep the service maintained, because these tools break when Instagram changes its backend and most others go silent.

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?

StealthPeek's answer

Our users are individuals: marketers, journalists, creators, partners, and parents.

Cert Decoder's answer:

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

What makes your product unique?

StealthPeek's answer

We are honest about the limits. Public accounts only, no credentials, no fake results, and we say plainly when something cannot be done, like viewing a private profile. That honesty is rare in this category.

  • Banana.dog back from the dead
    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
