Content
Dynamic Links
Static QR (Content section above): the destination is baked into the printed code forever.
Dynamic QR (this section): the code encodes a short /r/<slug> link you can repoint later — no reprinting. Anyone on your team can change or deactivate it, so label links clearly.
Fired on every scan with event data (https only).

Analytics
Activity

Recent changes to shared team resources — who created, repointed, or deleted what. Kept for the last 500 actions.

No activity recorded yet.
API Access

Personal API tokens for automation — scripts, scheduled backups, CI. A token acts as you (same permissions) and is shown only once, at creation. Example: curl -H "Authorization: Bearer qrb_…" …/api/projects

No API tokens yet.
Users

Create logins, reset passwords, and assign roles. Admins can manage users, change roles, delete anyone's shared items, and download backups. Operators can do everything else, but can only delete items they created.

Existing users
No users found.
Team settings
When off (default), any operator can repoint any link. Deleting a link always requires its creator or an admin, regardless of this setting.
Database backup
The .db is a consistent SQLite snapshot of everything — projects, presets, dynamic links, scan analytics, users, and the activity log. The .zip adds every uploaded logo plus restore instructions. Store either somewhere safe.

Save Project

Projects are shared with everyone on this QR Builder — name it so teammates can find it later.

Print Sheet

Arrange one or more QR codes on a printer-ready sheet, sized for common label and card formats.

Test with Camera
