Orbit 2 is a simple scaffolding you can build a Redux/MVI-like architecture around. In Orbit 2 we took the best features of Orbit 1 and have rewritten the rest from scratch.

What's new 🚀

Powerful and flexible design 🏋️‍♀️ 🤸‍♂️

• Integrates best practices from our 2+ years of experience with MVI
• Easy to use, type-safe API
• Powered by coroutines
• Extensibility - operator extensions and more provided via plugins
• Modularity - use the features you want without unnecessary dependencies
• Adapts to your codebase, rather than the other way round!

Works with any async/stream framework 🔀

• Coroutine operator support
• RxJava 1, 2 & 3 operator support
• LiveData operator support
• Ability to mix different kinds of operators, like RxJava and coroutines, within the same orbit flow
