Overview

Scanline is a self-hosted replacement for commercial QR code services: static and dynamic codes across 19 content types, a full design studio, hosted landing pages, and per-scan analytics with no third-party calls. Dynamic codes route through short links that can be edited, paused, expired, or capped after printing, with scans broken down by country, city, device, OS, and browser via offline GeoIP. It ships with custom domain support, a bearer-token public API with batch creation, and print-ready exports in PNG, SVG, PDF, and EPS.
