Show HN: Carton – Real Boundaries for Ruby

Category: library

Tags: ruby, modularity, dependency-isolation, ruby-box, boundaries

Score: 6.8/10 (Innovation: 8, Technical: 7, Documentation: 7, Utility: 5)

Carton introduces runtime-enforced module boundaries in Ruby using the experimental Ruby::Box feature, allowing per-Carton gem versions, isolated monkey patches, and explicit exports. It addresses real pain points in large Ruby apps where global constants and open classes cause cross-contamination, offering an in-process alternative to service extraction.

Target audience: Ruby backend developers, especially those maintaining large monolithic applications
