AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Validates URIs and URI-references against RFC 3986 standards using pure Python, returning a boolean result for whether a given string conforms to the specification.

Installation is frictionless with no runtime dependencies. However, the package is marked as abandoned with its last commit in December 2022 and no releases since October 2019, raising concerns about whether it will receive security updates or fixes for edge cases in RFC 3986 compliance.

Licensed under MIT (permissive), allowing free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Usage

pip install rfc3986-validator

from rfc3986_validator import validate_rfc3986
result = validate_rfc3986('http://foo.com/blah_blah_(wikipedia)')
print(result)  # True or False

Requires Python 2.7 or Python 3.5+; Python 3.0–3.4 are explicitly excluded.

Verdict: A lightweight, dependency-free RFC 3986 validator with permissive MIT licensing, but its abandoned maintenance status (no updates since 2019) means it may not handle newer URI edge cases or receive security patches. Suitable for simple validation tasks in stable environments, but riskier for production systems requiring ongoing compliance assurance.

Needs verification

Whether the validator correctly handles all RFC 3986 edge cases or known limitations in the specification
Whether the package has been tested against Python versions beyond 3.8 (current support claims are dated)
