If you want something simple and open source:

**qrencode** (CLI) — `qrencode -o output.png "your text"` — available on every Linux distro, fast, zero dependencies.

**Python** — `pip install qrcode[pil]` then:
```python
import qrcode
qrcode.make("your text").save("qr.png")
```
Three lines, works everywhere.

**Web-based** — goqr.me or qr-code-generator.com if you just need a quick one without installing anything.

I actually built a QR code API that generates them on the fly — DM me if you want the endpoint.
