OpenQR is a free, open-source QR code generator that runs entirely in your browser: no sign-up, no watermark, unlimited static codes. Style everything (colours, gradients, dot and corner shapes, logo embedding, frames), export PNG, JPEG and WebP up to 4096px plus true-vector SVG and PDF for print, and build whole sets in batch mode.
A free account adds an editable dynamic QR code: change where it points after printing, with privacy-friendly scan analytics. Developers get a free REST API (OpenAPI spec included) and a hosted MCP server with 20 tools, so Zapier, n8n, Make and AI agents can create and manage codes programmatically.
AGPL-3.0 licensed and self-hostable as a single Docker container: no database, no environment variables.
