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
