Overview
Nano ID Forge outputs compact, URL-friendly identifiers that stay collision-resistant even with short lengths. Tune the length to balance readability and entropy for public-facing links or device codes.
Use Cases
IoT or hardware pairing codes
Issue Nano IDs to pair devices and hubs during onboarding flows, yielding short codes that remain unambiguous when spoken aloud.
Lightweight database keys
Use Nano IDs as primary keys for high-traffic tables where compact strings reduce storage overhead and index size.
How to Use
Choose the desired length
Set a length between 4 and 40 characters. Shorter values improve ergonomics while longer ones increase entropy for security-sensitive contexts.
Generate the Nano ID
Click “Generate” to produce a new identifier drawn from the default Nano ID alphabet, optimised for URL and filename safety.
Integrate into your system
Copy the Nano ID into databases, invitation links, or pairing screens. Regenerate as needed to mint additional codes.
Frequently Asked Questions
What length should I use?
For public URLs, 7–10 characters provide a good trade-off between brevity and uniqueness. Increase to 16+ for security-critical tokens.
Can I customise the alphabet?
This UI uses the standard Nano ID alphabet (A–Z, a–z, 0–9, _ and -). For bespoke alphabets, integrate the underlying generator in code.
How resistant is Nano ID to collisions?
Nano ID offers better collision resistance than short UUIDs thanks to an evenly distributed alphabet and configurable length. Collisions remain statistically rare for recommended sizes.
