What is PySpring?

PySpring is a Python web framework inspired by Spring Boot. It brings the structured, convention-over-configuration approach of Spring Boot to Python — with type-safe dependency injection, component lifecycle management, and a FastAPI-based web layer.

Why PySpring?

Python has excellent web frameworks (FastAPI, Flask, Django), but most of them don't provide a strong opinion on application architecture. As projects grow, developers end up reinventing patterns that Spring Boot solved years ago:

• Dependency injection
• Configuration management
• Component lifecycle
• Event-driven architecture

PySpring brings these patterns to Python, using Python's type system instead of Spring's annotations.

Inspiration

PySpring takes direct inspiration from:

• Spring Boot — the overall architecture, DI patterns, and component model
• FastAPI — the web layer, automatic OpenAPI docs, and Pydantic integration
• Pydantic — data validation and configuration modeling
