Syzygy is a cross-platform mobile ecosystem — production-ready Foundation, UI, Core and Service libraries, plus starter templates, spanning iOS, Android, React Native, and Flutter.
The name comes from the astronomical term for when celestial bodies align — representing multiple platforms coming together into one cohesive, aligned ecosystem.
Every UI library ships with zero third-party dependencies and the same shared token system — colors, typography, spacing, radius — reproduced consistently across all four platforms, with full Dark Mode support built in from the start. Component naming and API shape stay deliberately consistent cross-platform (the same problem is solved the same way in SwiftUI, Jetpack Compose, React Native, and Flutter), and every repo shares the same CI pipeline and tag-gated release process.
Syzygy is a four-layer architecture. Each layer is independent and can be used without the others.

Contracts & primitives
- Foundation — contracts, primitives, shared types. Zero implementation. Every other layer depends on this.
- UI — visual component libraries with design tokens, theming, and dark mode. Zero business logic.
- Core — app infrastructure, navigation, DI, security, architecture utilities. (in progress)
- Services — networking, storage, analytics, OS integrations. (in progress)
