About the project

A compiler that reads Ruby source of Rails applications and transpiles them into standalone projects in Rust, Go, TypeScript, Crystal, Elixir, Kotlin, Swift, Python, C#, or Ruby, and compiles to a native binary via Spinel. The target language is a build flag, not a runtime choice.

Useful for

Run roundhouse check in CI to catch type and nil-safety issues in a Rails app without annotations
Transpile a Rails app to Go or Rust to run it without CRuby
Compile a Rails app into a single native binary via Spinel

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
