anyid

A unified Python library for generating a variety of unique identifiers.

anyid provides a simple and consistent interface for generating different kinds of IDs, from classic UUIDs to modern sortable identifiers like ULID and KSUID. It's lightweight, type-annotated, and has minimal dependencies.

Supported Identifiers

ID Type	Sortable	Length (chars)	URL Safe	Notes
CUID	Yes	25	Yes	Collision-resistant for horizontal scaling.
CUID2	No	24 (default)	Yes	An improved, more secure version of CUID.
KSUID	Yes	27	Yes	K-Sortable Unique Identifier.
NanoID	No	21 (default)	Yes	Secure, URL-friendly, and fast.
ShortUUID	No	~22	Yes	A shorter, URL-safe version of a standard UUID.
Snowflake	Yes	19 (integer)	No	Twitter's distributed, time-sortable ID generator.
ULID	Yes	26	Yes	Universally Unique Lexicographically Sortable Identifier.
UUID	No	36	No	The classic, ubiquitous UUID v4.
XID	Yes	20	Yes	Globally unique ID that is sortable by time.

Installation

pip install anyid

Usage

The API is simple and consistent across all ID types.

from anyid import cuid, ulid, uuid

# Generate a CUID
my_cuid = cuid()
print(f"CUID: {my_cuid}")

# Generate a ULID
my_ulid = ulid()
print(f"ULID: {my_ulid}")

# Generate a UUID (v4)
my_uuid = uuid()
print(f"UUID: {my_uuid}")
