-.admin, account, login...).The homepage keeps your last 10 links in a browser cookie (valid for 30 days) so you can find them again quickly. This is stored locally in your browser only - switching device/browser or clearing cookies removes this list (the links themselves keep working, only the history view is lost).
To keep your links accessible across devices, or to edit/delete them later, create a free account before shortening. Links created while signed in are tied to your account and manageable at /account/:
Links created anonymously (before signing in) are not automatically attached to your account.
Every submitted link is automatically scanned (domain/keyword blocklist plus AI) before it's created. Once live, a link is always in one of three states:
Each IP address can create up to 50 links per day to prevent abuse. Once the limit is hit, you'll need to wait until the next 24-hour window.
Every link comes with an auto-generated QR code (click the icon on the result to view/save it). Pro or SS tier accounts can upload their own logo (PNG/JPG/GIF/WEBP, max 3MB) in Account Settings - it gets embedded in the middle of the QR code for every new link you create from then on.
A signed-in account not yet upgraded by an admin uses the shared Guest level. Higher tiers unlock a few extra perks when creating/managing links - quick comparison:
| Tier | Random code length | Min. custom alias | Skip redirect wait | Custom QR logo |
|---|---|---|---|---|
| Guest | 10 chars | 10 chars | ||
| VIP | 6 chars | 6 chars | ||
| Pro | 4 chars | 4 chars | ||
| SS | 2 chars | 2 chars |
