## What it is
A Python dependency injection framework inspired by Google's Guice. It automatically and transitively provides dependencies, reducing boilerplate in larger applications while encouraging modular code through modules.

## Use cases
- manage dependencies in a large python application
- reduce constructor boilerplate with automatic injection
- wire up services with type-hint based DI
- replace manual singleton and factory patterns
- organize bindings into modules like Guice
- statically type-checked dependency injection in python

## When to choose
- you want a Pythonic, Guice-inspired DI framework with static type checking support
- you need multiple independent injector instances without global state
- you want nonintrusive DI that keeps constructors usable manually

## When to avoid
- your project is small and manual keyword-argument injection suffices
- you need member or method injection features
- you prefer a DI framework with global container access

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools
- domain: developer-tools, backend, web-development
- platform: python, cross-platform
- tags: dependency-injection, guice-inspired, type-hints, inversion-of-control
