RIPPLE

Ripple is a TypeScript UI framework that combines the best parts of React, Solid, and Svelte into one package. It was designed to be a JavaScript/TypeScript-first framework, rather than HTML-first. Ripple has its own superset language that plays nicely with TypeScript and JavaScript, but with an interesting touch that leads to a better developer experience for both humans and large language models. It is still in an early development stage.

OBS.JS

Obs.js is a JavaScript library that improves web performance by adapting websites to users' network conditions and battery status. It uses the Navigator and Battery APIs to gather contextual information, adding CSS classes to the `html` element and exposing data via the `window.obs` object. This allows developers to conditionally load assets or disable features based on the user's environment, optimizing the experience for both high and low-resource devices.
