Questions & Answers

As answered by people managing quackr and NumValidate.

What makes your product unique?

quackr's answer

Quackr stands out by offering a seamless bridge between free public access and premium private security. Unlike many competitors that rely solely on low quality VoIP numbers (which are often blocked), Quackr provides Private Non-VoIP Numbers sourced from real SIM cards. This ensures high deliverability rates for strict services like Tinder, Gmail, and Banking apps, giving users a level of reliability that standard free sites cannot match.

Which are the primary technologies used for building your product?

quackr's answer

Quackr is built on a robust cloud infrastructure designed for speed and security. We utilize advanced telecommunications APIs to bridge real world SIM networks with our digital dashboard, ensuring near instant SMS delivery. Our frontend uses modern frameworks (like React/Next.js) to ensure a fast, responsive experience on both mobile and desktop.

What's the story behind your product?

quackr's answer

Quackr started with a simple mission to stop SMS spam. We realized that requiring a personal phone number for every minor sign-up was a privacy risk. What began as a free tool to protect users from telemarketers has evolved into a comprehensive privacy platform, helping thousands of users globally verify accounts securely without exposing their real identity.

How would you describe the primary audience of your product?

quackr's answer

Our primary audience consists of privacy conscious professionals, digital marketers, and cybersecurity enthusiasts. This includes social media managers managing multiple accounts, developers testing authentication flows, and individuals who want to secure their personal data against data breaches. They are users who value their digital footprint and are willing to invest in secure, private verification methods.

Why should a person choose your product over its competitors?

quackr's answer

Competitors often provide recycled, spam filled numbers that fail verification checks. Users choose Quackr because we offer guaranteed privacy. With our paid rental option, users get a dedicated number that is theirs alone no shared messages, no interference. We combine the ease of a "one click" free service with the professional reliability of a paid private line, giving users the best of both worlds.

  • Ask HN: Is there a temp phone number like temp email?
    There are lots of them: https://quackr.io/ https://receive-smss.com/ https://sms24.me/ https://temp-number.com/ https://onlinesim.io/. - Source: Hacker News / 11 months ago
  • Did people really use "burner phones"?
    I'm also curious because it seems like using a phone with no strings attached today seems almost impossible unless you get an actually old phone, which either works poorly or costs a lot as part of a retro collection or something. Even my iPhone 4S doesn't work if I boot it up, and that came out last decade. Of course, in terms of using a number for making a new account or subscription of sorts, one could still be...

  • I'm back and the chair has never been stronger.
    You can also take this poll over at bettor edge, and whichever team gets the most votes, will get an extra 5k donated to their respective charity (the loser will still get a 1k donation). So if you are so inclined, head over there and vote for the huskers and Team Jack. Right now we're losing 65% to 35% to the gophers on who should get the extra donation so vote if you can! Note they ask for a phone number to... Source: almost 3 years ago
  • Why is Whatsapp so popular in India?
    To be very frank, I was also thinking that another reason people tend to use Whatsapp is that itโ€™s not really tied to any actual account as in the case of iCloud, right? Itโ€™s just a phone number thatโ€™s required, and so if you want to stay private, or just log in with a fake account, you can use a free phone number for verification, just as you would do with some disposable temporary mail when you want to log in to...

  • Has anyone used temporary phone numbers for app registration worth it?
    While searching for another way out, I stumbled upon a service called quackr.io. It claims to provide temporary phone numbers for registration confirmation purposes. Using fake numbers for app verification is quite tempting, and I read that it's a savior when it comes to website registration. Still, I'm unsure if it's worth the effort because I also read many claiming that temporary phone numbers don't work with... Source: about 3 years ago
