## What it is
A Go implementation of the nanoid algorithm for generating compact, URL-safe unique identifiers using a cryptographically strong random generator. It produces 22-character IDs with the same uniqueness as UUIDs and supports custom alphabets and lengths.

## Use cases
- generate short unique IDs in Go
- replace UUIDs with compact URL-safe identifiers
- generate random IDs with a custom alphabet
- create database record keys that are safe in URLs
- generate session or request identifiers
- produce compact IDs for distributed systems

## When to choose
- you need compact, URL-safe unique IDs in a Go project
- you want UUID-level uniqueness in fewer characters
- you need custom alphabets or ID lengths
- you want a small, dependency-free ID generator

## When to avoid
- you need IDs that integrate with database UUID support
- you want a maintained, feature-rich ID solution like typeid
- you need sequential or sortable IDs
- you require strict cryptographic guarantees beyond standard CSPRNG usage

## Facets
- artifact type: library
- maturity: maintenance
- function: security, serialization, developer-tools
- domain: developer-tools, web-development, backend
- platform: go, cross-platform
- tags: nanoid, unique-id, uuid-alternative, random-id-generation, url-safe-ids
