Hi Product Hunt 👋
I built qr3.app because QR infrastructure is still split between simple generators that stop at an image and enterprise platforms that hide everything behind a sales call. Developers need an API they can ship with, while manufacturers face a new layer of EU Digital Product Passport requirements.
qr3.app brings both into one developer-first stack: dynamic QR codes, scan analytics, webhooks, batch APIs, a TypeScript SDK and CLI, an MCP server for AI agents, plus GS1 Digital Link and battery/textile DPP validation. It runs on Cloudflare's edge, starts with a free tier, and is designed for privacy from the first scan.
I’d love your feedback on the API and developer experience — and especially which DPP workflow or SDK you want next.
