A ready-to-use and customizable user management system for FastAPI applications.
FastAPI Users is a Python library that provides a ready-to-use and customizable user management system for FastAPI applications. It solves the problem of implementing secure authentication, registration, and user management by offering pre-built routes, multiple authentication strategies, and extensible models. This allows developers to quickly add robust user functionality to their APIs without reinventing the wheel.
Backend developers building FastAPI applications who need to implement user authentication, registration, and management features efficiently. It's particularly useful for projects requiring customizable security implementations and support for multiple database backends.
Developers choose FastAPI Users because it provides production-ready user management with full OpenAPI support while maintaining high customizability. Unlike building from scratch, it offers multiple authentication backends, social OAuth2 flows, and database adapters out of the box, saving significant development time.
Ready-to-use and customizable users management for FastAPI
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The base user model is fully customizable, allowing developers to add custom fields to fit their data schema without modifying core logic, as highlighted in the README's features list.
Provides ready-to-use endpoints for registration, login, password reset, and email verification, saving significant development time and ensuring security best practices are followed.
Supports JWT, database, and Redis authentication with both header and cookie transports, offering flexibility for different security needs and application architectures.
Includes adapters for SQLAlchemy async ORM and MongoDB with Beanie ODM, enabling seamless integration with popular databases without requiring custom implementations.
Generates complete OpenAPI schemas automatically, even when using multiple authentication methods, ensuring API documentation is always accurate and up-to-date.
The README explicitly states the project is in maintenance mode with no new features added, limiting its long-term viability for teams needing updates or community-driven enhancements.
Setting up requires configuring database backends, authentication strategies, and custom models, which can be overwhelming compared to simpler, drop-in solutions.
It's designed exclusively for FastAPI, so migrating to another framework would necessitate a complete rewrite of the authentication system, adding technical debt.
While it supports multiple backends, adding unsupported databases or authentication methods requires significant custom development, as the library focuses on provided adapters.
