Lucia vs T3: What are the differences?

Lucia: 3kB Vue Alternative. It is a tiny JavaScript (UMD compatible) library that serves as a bridge between vanilla JavaScript and Vue. It provides a declarative API similar to Vue/Alpine to create views, making development predictable and intuitive through markup-centric code; T3: Client-side JavaScript framework for building large-scale web applications, created by Box. T3 is different than most JavaScript frameworks. It's meant to be a small piece of an overall architecture that allows you to build scalable client-side code. T3 is explicitly not an MVC framework. It's a framework that allows the creation of loosely-coupled components while letting you decide what other pieces you need for your web application. You can use T3 with other frameworks like Backbone or React, or you can use T3 by itself.

Lucia and T3 belong to "Javascript UI Libraries" category of the tech stack.

T3 is an open source tool with 1.59K GitHub stars and 157 GitHub forks. Here's a link to T3's open source repository on GitHub.
