I'm part of a small team that builds free web tools. MakeQR is a QR code generator that runs entirely in the browser. Why I built it: many free generators encode a short link that redirects through their own server, so a printed code stops working when a trial ends or the service shuts down. MakeQR writes your content straight into the code (URL, text, Wi-Fi, vCard, email, phone, SMS, location, event). There is no redirect and no account, so a printed code keeps working even if this site disappears. The trade-off is that you can't change the destination later or count scans. How it's built: static pages served from Cloudflare Workers. Rendering uses the open-source qr-code-styling library, vendored. Output is PNG, SVG or JPG from 200 to 2000 px, with colors, dot and eye shapes, an optional logo and a caption. What you type is not sent to a server. The one exception is the optional group check-in room, which needs a small backend to share the arrival list. The page shows ads and an Amazon affiliate link. Feedback I'd find useful: codes that fail to scan on your phone (especially with a logo or custom shapes), and anything confusing in the Wi-Fi or vCard forms.
