Metro, a Kotlin compiler-based dependency injection framework, has reached version 0.10.0 and is now production-ready. The author, currently funemployed and working on open source full-time, is opening GitHub Sponsors to support continued development. Metro delivers 50-80% build time improvements over Dagger and is already used in production at Block, OpenAI, and Dropbox. Cash App reported a ~60% reduction in incremental build times after migrating. Sponsorship tiers range from $5/month for individuals to $500/month for companies, and Metro will remain free and open source regardless.
