## What it is
OAuthLib is a Python framework implementing the OAuth 1.0 (RFC 5849) and OAuth 2.0 (RFC 6749) request-signing and authorization logic in a spec-compliant way. It is framework- and HTTP-library-agnostic, letting developers graft OAuth client or provider support onto any HTTP library or web framework with a thin veneer.

## Use cases
- add OAuth2 login to my Python web app
- implement an OAuth1 request-signing client
- build an OIDC provider in Python
- add OAuth support to a custom HTTP library
- validate OAuth bearer and JWT tokens
- implement OAuth2 provider endpoints for my API

## When to choose
- you need spec-compliant OAuth1/OAuth2 logic decoupled from any specific HTTP framework
- you are a library maintainer wanting to add OAuth support with minimal effort
- you need OpenID Connect or JWT bearer token handling in Python

## When to avoid
- you want a batteries-included OAuth integration for a specific framework like Django or Flask (use framework-specific wrappers like requests-oauthlib or django-oauth-toolkit)
- you need a turnkey hosted identity solution
- your project is not in Python

## Facets
- artifact type: library
- maturity: stable
- function: auth, authorization, middleware
- domain: security, web-development, apis, developer-tools
- platform: python, cross-platform
- tags: oauth1, oauth2, openid-connect, jwt, request-signing, framework-agnostic
