As answered by people managing HackerRank and StealthPeek.
StealthPeek's answer:
Our users are individuals: marketers, journalists, creators, partners, and parents.
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.
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.
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.
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.
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.
