SDN.ac is a fast and simple URL shortener for creating clean, secure links without unnecessary setup. Create a short link instantly, then add an expiration date, password protection, or one-time access. Every link also comes with a QR code, ready to share. For automated workflows, SDN.ac provides a straightforward API that lets apps, bots, and SaaS products generate short links programmatically. No account required. Just quick, reliable links for people and applications.

Every URL shortener I tried wanted an account before it let me do anything. So I stopped signing up. SDN.ac is what I built instead. Paste a link. You get a short one. If you need an expiry, a password, one-time access, or a QR code, those are there too. No dashboard. No verification email. No onboarding. There’s also a small API if you’re generating links from a script or an app. That’s the part I’m least sure about, so I’d rather hear what you’d actually expect from it than ship the wrong thing. Two honest questions: Is skipping the account useful to you, or does it make the link feel less trustworthy? And if you try the API, what would make it fit cleanly into your workflow? Still early. I’m watching before I build more.
