What is Nano ID?
Nano ID is a compact unique ID format designed for modern applications. It gives you short, clean identifiers that are easier to read and share than classic UUID strings while still keeping strong uniqueness.
Compared with UUID, Nano ID is usually shorter and looks cleaner in URLs, dashboards, and API responses.
Use Cases
- Invite codes for onboarding and referrals.
- URL slugs for short links and shareable pages.
- Frontend keys for React/Vue rendering and local state maps.
- Lightweight database IDs for records that do not need long UUID strings.
Why use Nano ID instead of UUID?
- Shorter length reduces visual clutter.
- Better fit for URL paths, invite links, and human-facing UI.
- Still highly unique when generated with crypto-safe randomness.
How to customize Nano ID?
- Adjust length based on your uniqueness target and readability needs.
- Choose a preset mode:
- URL Safe for web links.
- Alphanumeric for strict letters and digits only.
- Custom mode for your own character mix.
- Fine-tune character groups (lowercase, uppercase, numbers).
- Optionally exclude similar characters to improve readability in manual sharing.
