A while back I needed dynamic QR codes for a small project and kept hitting the same wall: either the free tier was too limited, or the code stopped working the moment my trial ended.
So I built QR/Go. Free tier includes 10+ static QR types (URL, text, WiFi, contact cards, and more) and 2 dynamic QR codes, no card needed to try it. Even if you cancel, dynamic codes keep redirecting to their last saved link. You only lose editing and scan analytics until you resubscribe, never the code itself.
Happy to answer questions if anyone's dealing with the same annoyance. It's at https://www.qr-go.app if you want to try it. Genuinely curious what other pain points people have hit with QR tools too.
