## What it is
Hologram is a full-stack isomorphic Elixir web framework that runs on top of Phoenix, letting developers build dynamic, interactive web applications entirely in Elixir. It intelligently compiles the client-side parts of your Elixir code to JavaScript, so no JavaScript frameworks or direct JS coding are required.

## Use cases
- build interactive web apps entirely in Elixir without writing JavaScript
- create SEO-friendly server-side rendered pages that hydrate on the client
- manage UI state in the browser for snappy interfaces
- build component-based UIs with reusable Elixir components
- stream server-pushed updates to clients without WebSockets
- avoid maintaining separate frontend and backend codebases

## When to choose
- your team knows Elixir and wants a single language across client and server
- you want Phoenix-based apps with rich client-side interactivity without JavaScript frameworks
- you need SSR for SEO plus client-side state for responsiveness
- you prefer convention-over-configuration and component-based architecture

## When to avoid
- you need a mature ecosystem with a large community and abundant libraries
- your project requires heavy custom JavaScript or specific JS frameworks like React
- you need non-browser targets like native mobile apps
- you want a framework with long-term enterprise track record
