Smart Networking is a free, open-source web app that turns every link you own—profiles, products, projects, and contacts—into a QR code on one mobile page. When you meet someone in person, you don’t dictate, type, or promise to “send it later.” You show your screen, they scan, and done. It installs like a native app on iOS and Android straight from the browser, works fully offline, and requires no account.

Why I built it
Online, sharing a link takes one click. Offline, the same task falls apart. At every conference and meetup, I watched the same scene—including in the mirror: someone asks for your LinkedIn, and you’re suddenly juggling apps in a noisy hallway, searching your own profile, spelling out an email address. Or you mention your book or a recent article, promise to “send the link,” and the moment quietly dies there. Nobody sends it. Nobody asks twice.
I’m a senior marketing director, not a developer. I built Smart Networking as a personal side project—evenings and weekends—to remove that friction for myself first. Claude (Anthropic’s AI) wrote most of the code; I did the product thinking: what to build, what to cut, and how it should feel in a real conversation. The full journey, mistakes included, is public in the GitHub commit history.
Who it’s for
Anyone whose work spills across many links and who meets people face to face:
• Marketers and consultants who network at industry events
• Founders and product people who demo and pitch in person
• Speakers and authors—your book, talks, and articles live on different platforms
• Sales and business development — the fastest possible contact exchange
• Anyone building a personal brand across LinkedIn, X, Substack, YouTube, and beyond
The common thread: your professional identity is spread across a dozen URLs, and the person in front of you needs exactly one of them—right now.
How it works
1. Open one page. Your links live on a single mobile screen, grouped into tabs you can rename — Business, Personal, Hobby, or anything else.
2. Tap a card. A large QR code fills the screen. The other person points their camera—no app needed on their side—and lands exactly where you wanted: your LinkedIn, your product page, or your Calendly.
3. Or copy instead. Every link also copies to the clipboard in one tap, ready to paste into any chat. Prefer texting it? Two seconds.
Try it with my live card: the demo at smart-networking. khomichenko.com is my actual working profile. Tap Edit and my details become placeholder hints — type your own over them, and the card is yours. Everything you enter is saved only in your browser.
What’s inside
• A QR code for every link—LinkedIn, website, podcasts, socials, anything with a URL
• One-tap copy for every link—the page doubles as your personal link vault
• Pinned favorites—keep up to five links on top and re-pin them as your day changes
• Renamable tabs to organize a large link collection
• A built-in editor—make the card yours in two minutes, no signup
• 28 icons: popular platforms plus generic glyphs for custom links
• Installs like a real app on iOS and Android—home screen icon, full screen, no App Store
• Works fully offline: QR codes are generated on your device, so everything scans with zero signal
Privacy by architecture, not by promise
Smart Networking has no accounts, no backend, and no database — so there is nothing to collect and nowhere to leak from. Your edits are stored in your browser’s local storage, on your device. After the page loads, nothing is transmitted anywhere; you can verify this in the source code, because all of it is open. The honest trade-off: your edits live in one browser on one device. Clear your site data and you’re back to the demo. For a permanent card, fork the repository and make it truly yours.
How it compares
| Smart Networking | Linktree-style pages | Paper business cards | NFC cards | |
| Built for | In-person moments | Online bios | In-person | In-person |
| Works offline | Yes, fully | No | Yes | Needs the other phone online to open the link |
| Account required | No | Yes | — | Usually |
| All your links | Yes, organized in tabs | Yes | One or two | Usually one URL |
| Cost | Free, open source | Free tier + paid plans | Printing costs | Hardware cost |
| Can be edited on the spot | Yes, built-in editor | Yes, in the dashboard. | No | Rewriting required |
When you don’t need it
Honesty section. If all your networking happens online, a link-in-bio page serves you better. If you need one card synced across three devices and a team, you need a service with accounts—that is a deliberate non-goal here. And if you only ever share a single link, your phone’s built-in QR share does the job. Smart Networking earns its place when your links are many and your meetings are physical.
The AI experiment behind it
This project doubled as an experiment: can a marketing leader ship a real, working product with AI-assisted coding? The answer turned out to be yes — with a caveat worth stating. Claude handled the engineering components, the offline layer, and the editor. What it could not replace was the product work — deciding what matters, cutting what doesn’t, testing the flow in real conversations, and writing every word of positioning. The commit history on GitHub documents the whole collaboration, and I’d recommend the experiment to any non-developer with a real problem to solve.
FAQ
Is Smart Networking free?
Yes, completely. There is no paid tier and no business model — it’s a personal side project, open-sourced under the MIT license.
Does it work on iPhone and Android?
Yes. On both platforms it installs straight from the browser: Android offers “Install app”; on iPhone, use Share → Add to Home Screen. You get a home-screen icon and a full-screen app that works offline.
Where is my data stored?
Only in your browser’s local storage on your device. The app has no server, no database, and no analytics — nothing is uploaded anywhere.
What happens if I clear my browser data?
Your edits are removed and the page returns to the demo profile. It takes a couple of minutes to set your card up again — or fork the repository on GitHub to make your data permanent on your own URL.
Can I put it on my own domain?
Yes. Fork the GitHub repository, edit one configuration file with your name and links, deploy free on Vercel, and attach your domain. The MIT license only asks that the copyright notice stay in place.
Do people I meet need to install anything?
No. They point their phone camera at your QR code — the standard camera app on both iOS and Android reads it natively.
Where can I follow the launch?
Smart Networking launches on Product Hunt on August 13, 2026. Before that date you can follow the “coming soon” page to get notified; on launch day the same link opens the live listing where you can try it and leave feedback: [Product Hunt link].
