Free QR Code API with No Signup — Generate QR Codes Programmatically
Free QR Code API — No Signup Required for Testing
Need to generate QR codes in your app? Most QR code APIs require you to create an account before you can even test them. Here's one that lets you sign up in 10 seconds and start generating immediately.
Why an API Instead of a JavaScript Library?
JavaScript QR code libraries like qrcode.js work great for simple cases. But an API gives you:
- Server-side generation — generate QR codes in any language (Python, Ruby, Go, PHP)
- Consistent SVG output — perfect for print materials
- Custom branding — custom colors without managing rendering
- No client-side dependencies — keep your bundle size small
- 100 QR codes per day
- No credit card
- All features included (custom colors, SVG, error correction)
- Signup: https://api.16761.tech/signup
