## What it is
Om is a ClojureScript UI framework built on top of Facebook's React, providing a client/server architecture inspired by Relay, Falcor, and Datomic pull syntax. It offers snapshotable and undoable UI state with minimal implementation complexity.

## Use cases
- build web UIs in ClojureScript with React
- manage client/server state without incidental complexity
- create snapshotable and undoable interfaces
- write React components using ClojureScript idioms
- explore Relay/Falcor-style data fetching patterns

## When to choose
- you are maintaining an existing Om codebase
- you want a historical reference for ClojureScript React wrappers
- you prefer Fulcro's lineage and want to study its predecessor

## When to avoid
- starting a new project - the project is no longer under active development
- you need a well-maintained alternative - use Fulcro instead
- you need React 18+ features or modern tooling support

## Facets
- artifact type: library
- maturity: abandoned
- function: frontend-framework, ui-components, state-management
- domain: web-development, frontend
- platform: browser, cross-platform
