What It Is

QR Fabric is a privacy-first static QR code generator that offers both a web interface and a public HTTP API. It emphasizes “in-memory” processing: submitted QR code content is not stored in a database, and uploaded logos are processed only in memory and are not saved. For users who need to generate QR codes quickly but do not want their content retained long-term by a third-party service, this is a clear selling point.

Core Features

The web interface supports a wide range of QR code types, including links, text, email, phone, SMS, WhatsApp, Wi‑Fi, vCard, social media, events, apps, and crypto. For visual customization, it supports solid colors, gradients, foreground/background colors, eye colors, transparent backgrounds, logo uploads, logo sizing, and settings for the QR code body, eye frames, and eye shapes. For output, it explicitly supports PNG and SVG downloads, while PDF/EPS options also appear on the page but are not sufficiently explained.

Developer support is one of the product’s stronger areas. QR Fabric exposes two endpoints: POST /api/v1/qr/png and POST /api/v1/qr/svg, and provides /docs Swagger UI as well as /openapi.json. The PNG API supports payload, error correction level, box size, border, fill color, background color, transparent background, logo scaling, and logo files; the SVG API mainly supports payload, error correction level, box size, and border.

Pricing and Limitations

Static QR codes generated through the web interface are labeled as 100% free. API use, however, is limited to open-source and non-profit projects; any commercial or closed-source use requires contacting the maintainer first. The text does not disclose commercial pricing, usage quotas, rate limits, or an SLA.

Pros and Cons

The advantages are that it is easy to get started with, requires no login, has a clear privacy statement, and provides a standard OpenAPI, making it suitable for scripts and server-side integrations. The drawbacks are that the product scope is relatively lightweight: there is no visible support for dynamic QR codes, scan analytics, batch management, team collaboration, or similar features. In addition, its open-source status, self-hosting options, commercial licensing, and support channels are not clearly defined.

Who It’s For / Access from China

It is better suited to individuals, open-source projects, non-profit organizations, and small developer projects that need to embed QR code generation capabilities. If a company wants to rely on this API long-term in a commercial system, it should first confirm licensing, stability, and support commitments. Access from mainland China cannot be determined from the text alone, so hands-on testing is recommended.
