A non-intrusive, header-only dependency injection container for C++11 and later that automates wiring and reduces boilerplate.
Kangaru is a dependency injection container for C++11, C++14, and later versions. It automates the wiring of dependencies in C++ applications, reducing boilerplate code by providing autowiring, constructor injection, and function parameter injection. The library helps manage object lifetimes and dependencies in a non-intrusive way.
C++ developers building applications with complex dependency graphs who want to reduce manual wiring and improve code maintainability. It's particularly useful for projects using modern C++ standards (C++11 and later).
Developers choose Kangaru for its non-intrusive design, header-only simplicity, and compile-time safety. It offers a clean API with low runtime overhead, making it a lightweight yet powerful alternative to manual dependency management in C++.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Requires no modifications to existing classes, allowing seamless integration into legacy codebases without altering core logic, as emphasized in the README's philosophy.
Provides clean diagnostics and errors at compile-time, ensuring dependency issues are caught early without runtime surprises, which is a highlighted feature for reducing bugs.
Supports autowiring, constructor, function parameter, and setter injection, giving developers multiple ways to manage dependencies based on specific use cases, as demonstrated in the overview examples.
Easy to add to projects with no separate compilation steps, simplifying build processes and reducing deployment complexity, which is a key feature mentioned in the installation section.
Extensive use of templates can significantly increase compilation times, especially in large projects with many dependencies, a common trade-off with header-only C++ libraries.
Focused on compile-time configuration, making it less suitable for dynamic dependency resolution or scenarios requiring runtime changes, which the README acknowledges as an area for future improvement with 'service sources'.
As a niche C++ library, it has fewer third-party integrations, community resources, and documented real-world usage compared to more established dependency injection frameworks, limiting support options.
