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
