Rage is an API-first Ruby web framework that combines the developer experience of Rails with fiber-based concurrency. You write standard synchronous Ruby code while Rage handles concurrency, running APIs, background jobs, and real-time communication in a unified runtime.
The framework uses Rails compatibility as a foundation while providing backend primitives designed for modern API systems.
This is free and open source software.
Key Features
- Familiar Rails-compatible controller API, routing DSL, and conventions.
- Fiber-based concurrency handles I/O without threads, locks, or async/await syntax.
- Zero-dependency WebSockets with Action Cable-compatible real-time features.
- Native Server-Sent Events streaming.
- Automatically generates OpenAPI documentation from controllers.
- Durable in-process background job queue.
- Built-in observability and telemetry.
- Object-oriented domain event system.
