## What it is
Rage is an API-first Ruby web framework that combines Rails-compatible ergonomics with fiber-based concurrency, running web requests, WebSockets, SSE, and background jobs in a single process. It aims to reduce infrastructure complexity by eliminating the need for separate worker processes, Redis, and external queue systems.

## Use cases
- build high-concurrency REST APIs in Ruby
- stream LLM responses with server-sent events
- add real-time WebSockets to a Ruby app without Action Cable dependencies
- run background jobs without Redis or Sidekiq
- auto-generate OpenAPI docs from controllers
- migrate a Rails API to a faster runtime
- build live dashboards and chat apps

## When to choose
- you want Rails-like developer experience with better concurrency
- you want a single-process stack without Redis or separate workers
- you're building API-only services with WebSockets or SSE streaming
- you need auto-generated OpenAPI documentation

## When to avoid
- you need a full-stack framework with views and server-side rendering
- your team depends on Rails-specific gems and ecosystem tooling
- you require very long-term battle-tested stability for critical systems
- you're on Ruby versions older than 3.3
