Ruby Next is an open-source tool that lets developers write modern Ruby syntax while maintaining compatibility with older Ruby interpreters, using transpilation and polyfills — similar to how Babel works for JavaScript. Rather than waiting for a full runtime upgrade, teams can adopt newer language features incrementally, then remove Ruby Next once the runtime is fully upgraded. While less universally needed now that Ruby 3.x is widely adopted, it remains valuable for large Rails monoliths, enterprise apps, and teams managing complex upgrade paths where decoupling language modernization from runtime upgrades reduces migration risk.
