## What it is
A lightweight Python library for validating simple values like emails, URLs, and IPs without defining schemas or forms. It provides simple functions that return True or validation errors.

## Use cases
- validate email addresses in python
- check if a string is a valid url
- validate ip addresses without a schema
- simple data validation for python
- validate user input in a flask app
- check domain name validity

## When to choose
- you need quick, schema-free validation of individual values
- you want a small dependency with simple True/False validation functions

## When to avoid
- you need complex nested schema or form validation with detailed error reporting
- you are validating structured documents rather than single values

## Facets
