StackQR is a free static QR code generator that lets you create codes by describing what you need in plain English. Type "wifi CaféNet password latte123" and your WiFi QR code appears instantly. No forms to fill out, no dropdowns to navigate, no learning curve to climb.
Your data never leaves your browser. We built it that way on purpose.
If you've ever searched for "free QR code generator," you know the frustration. Most results lead to tools that seem free at first but reveal the catch later: your code expires after 14 days, you need to create an account, or the "free" download is actually a low-resolution preview that pushes you toward a paid plan.
The QR code industry has a trust problem. App stores are filled with one-star reviews from people whose business cards, restaurant menus, or event flyers stopped working because their QR codes expired. Dynamic QR services charge monthly fees to keep codes active. What should be a simple utility has become a recurring revenue trap.
StackQR exists because we wanted something different. A QR code generator that actually means "free." Static codes that work forever because they encode the data directly. No redirect servers, no expiration dates, no subscriptions. Your WiFi password and contact details never touch a server because everything runs in your browser.
We're not trying to upsell you. There's no premium tier waiting behind a paywall. StackQR does one thing well: create permanent QR codes quickly and privately.
StackQR is built and maintained by Kamal Kumar, a software engineer and founder of Simple Mode LLC. Before starting Simple Mode, Kamal spent 20+ years building web applications at enterprise scale. That experience showed him how often simple tools get buried under unnecessary complexity.
StackQR grew out of a real frustration: needing a quick WiFi QR code for a guest network and discovering that every "free" generator either required an account, watermarked the output, or expired the code after two weeks. The fix shouldn't require a monthly subscription, so he built one that doesn't.
Simple Mode LLC is a software company focused on building straightforward SaaS tools that respect users' time and privacy.

Unlike dynamic QR codes that redirect through a tracking server, StackQR creates static QR codes. The difference matters:
For most use cases (business cards, WiFi sharing, restaurant menus, event flyers, product packaging) static codes are the better choice. They're simpler, more reliable, and completely free to maintain forever.
Everything StackQR does happens in your web browser. When you type your WiFi password or phone number, that data stays on your device. We never see it, never store it, never have access to it.
There's no account to create because we don't need to track you. There's no "cloud sync" because your QR codes don't need to live on our servers. The tool runs entirely client-side, so your sensitive information (network credentials, contact details, private messages) remains private.
