Link in Bio — without a vendor
Linktree, Beacons, Carrd, Lnk.Bio — every major link-in-bio service makes you sign up, puts your data on their servers, and can paywall or shut down your page at any time. You don't own your link page.
Abundera QR's Link-in-Bio generator is different: the entire bio page lives inside the QR's URL. Your display name, bio, avatar, and every link are encoded into a base64url hash appended to https://qr.abundera.ai/bio/. The /bio/ page is a tiny static HTML file that reads the hash, decodes it locally, and renders the page. No backend, no account, no vendor lock-in.
How to build one
- Fill in your display name, optional bio line, and optional avatar URL.
- Add up to 10 links with title + URL (Twitter, Instagram, Website, etc.).
- Click generate. The QR encodes a
https://qr.abundera.ai/bio/#...URL. - Scan with any phone. The page loads with all your links.
Capacity
QR codes at error-correction level H hold ~1273 characters. The URL prefix is ~35 chars, leaving ~1240 for the encoded payload. That's enough for ~900 bytes of JSON — roughly 10 links with short titles and URLs.
Privacy promise
Abundera QR never sees your bio page contents. URL fragments (#hash) are never transmitted to servers — that's RFC 3986 behavior, enforced by every browser. Your bio data lives in the client and is only decoded client-side by the /bio/ page's JavaScript.
Frequently Asked Questions
Is this really private?
Yes. URL fragments (#hash) are never sent to the server — that's RFC 3986 behavior, enforced by every browser. Your bio data lives in the client and is only decoded client-side by the /bio/ page's JavaScript.
What if Abundera goes away?
The /bio/ page is ~4 KB of HTML + JS. You can save it, host it anywhere (GitHub Pages, Netlify, your own server), and your QRs keep working.
How many links can I fit?
Up to 10 in the UI, but the real limit is QR capacity. Short titles + short URLs → all 10 fit comfortably.
Can I edit my bio later?
You'd need to regenerate the QR with the updated data — the QR is static. For truly dynamic bios you'd need a backend, which breaks the privacy promise.
Does it work offline?
Once the /bio/ page is cached by the service worker, yes — the renderer is pure client-side and the data is in the URL.
