## What it is
Volt is a Ruby web framework in which the same Ruby code runs on both the server and the client (compiled via Opal), with reactive DOM updates and automatic data syncing over a persistent connection. It offers server-side rendering for initial page loads, URL-based state, and reactive templates with Ruby embedded between {{ }}.

## Use cases
- build reactive single-page apps in pure Ruby
- write isomorphic Ruby code that runs on server and client
- auto-sync database changes to all connected clients in real time
- server-render initial HTML for SEO and fast loads, then render on client
- build apps with reactive templates that update the DOM automatically
- store page state in the URL for shareable links

## When to choose
- you want a full-stack Ruby framework with reactive, real-time data syncing and no JavaScript
- you need isomorphic Ruby with server-side rendering and client-side interactivity
- you are exploring reactive programming patterns in Ruby

## When to avoid
- you need a maintained framework with active support and security updates (last release was 2018)
- you need a large ecosystem, hiring pool, or production-grade guarantees
- your team prefers mainstream JavaScript/TypeScript frontend stacks

## Facets
- artifact type: framework
- maturity: abandoned

- domain: web-development, frontend, backend
