## AI interpretation — verify before relying

OAuthLib implements the core OAuth 1.0 and OAuth 2.0 request-signing logic in a framework-agnostic way, letting you add OAuth support to any HTTP library or web framework without assuming a specific implementation.

Verdict: OAuthLib is a mature, actively maintained, zero-dependency foundation for OAuth support across Python frameworks. With no known vulnerabilities, permissive licensing, and broad Python version support (3.8–3.13), it is a reliable choice for projects needing spec-compliant OAuth logic without framework lock-in.
