furl
URL manipulation made simple.
Decision gist · record as of 2026-08-14
Yes. furl is production-stable, actively maintained, has minimal dependencies, carries no known vulnerabilities, and solves a genuine friction point in URL manipulation. Use it when you need to programmatically build or modify URLs more often than you'd use raw urllib—it will save you string-handling boilerplate and reduce bugs from manual encoding.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
furl is a lightweight Python library that wraps URL parsing and manipulation into an intuitive object model. Instead of juggling urllib's functions, you work with a furl object whose attributes (scheme, host, path, args, fragment) map directly to URL components. Path segments and query arguments are stored decoded internally, so you manipulate them as plain strings; encoding happens automatically when you serialize back to a URL string. The library handles Unicode, percent-encoding, and fragment paths with their own query strings.
It's designed for the common case: you have a URL, you want to add or remove query parameters, change the path, or inspect components—and you want to do it without wrestling with string parsing. furl supports Python 3 and PyPy3, has no external C dependencies, and carries no known security vulnerabilities.
Use it for
- Building or modifying URLs programmatically in web scrapers or API clients without manual string concatenation.
- Adding, removing, or updating query parameters on an existing URL while preserving other components.
- Parsing URLs to extract and inspect individual components (host, path segments, query args, fragment).
- Handling URL encoding and Unicode automatically when constructing URLs with non-ASCII characters or special characters.
- Working with URL fragments that have their own path and query structure, common in single-page applications.
