Nano ID

Tiny, URL friendly IDs.

Easier to work with than UUIDs e.g. you can double click and copy them from a URL. Uses more (configurable) characters than UUID so the ID size can be reduced (also configurable). Faster to generate than UUID. Collision probability can be calculated based on config values so you can trade off usability for chance of collision. Available for lots of languages.
