Alpine.js is described as 'offers you the reactive and declarative nature of big frameworks like Vue or React at a much lower cost' and is an app in the Development category. There are nine alternatives to Alpine.js for a variety of platforms, including Online / Web-based, Self-Hosted solutions, Mac, Windows and Linux. The best alternative is React, which is both free and Open Source. Other great apps like Alpine.js are AngularJS (Free, Open Source), Meteor (Free, Open Source), ember.js (Free, Open Source) and RiotJS (Free, Open Source).
You can write less code with Ember's Handlebars integrated templates that update automatically when the underlying data changes. Ember.js incorporates common idioms so you can focus on the development of your application ( and not reinventing the wheel ).
Riot lets you build user interfaces with custom tags using simple and enjoyable syntax. It uses a virtual DOM similar to React but faster. Riot is very tiny compared to industry standards. We think there is a clear need for another UI library.
