It supports isomorphic rendering through streaming server-side rendering and progressive hydration, allowing content to be generated on both the server and the client. The system covers declar

Backstage is an open-source framework for building internal developer portals. It provides a centralized, metadata-driven software catalog that tracks ownership, dependencies, and lifecycle status for all technical assets by harvesting configuration files directly from version control systems. The platform is built on a plugin-based modular architecture, allowing teams to extend core functionality through isolated, independently deployable modules that integrate into a unified frontend and backend ecosystem. The project distinguishes itself through its focus on developer productivity and stan

Accompanist is a Jetpack Compose extension library providing a set of utility components and libraries that fill functional gaps in the declarative UI framework. The project provides an adaptive layout toolkit for building user interfaces that automatically adjust based on Android screen size and device configuration. It includes a renderer for converting standard Android Drawable assets into formats compatible with a declarative painting system, as well as a manager for requesting and tracking Android system permissions.
