A Python library for standardizing and normalizing URLs. Ideal for database deduplication, caching, web crawling, and anywhere you need to ensure that equivalent URLs resolve to the exact same string.

```python
from url_normalize import url_normalize

# Fixes IDN, lowercases host/scheme, removes default ports, resolves path...

## AI interpretation — verify before relying

Standardizes and normalizes URLs by handling internationalized domain names, lowercasing schemes/hosts, removing default ports, resolving path segments, and optionally filtering query parameters—useful for deduplication, caching, and web crawling.

Verdict: A well-maintained, lightweight URL normalization library with RFC-compliant handling of IDN domains, path segments, and query parameters. No security issues, low install friction, and permissive licensing make it a solid choice for applications requiring robust URL standardization.
