Sustainable AI Application Development

PackageJS + Claude Code generated 99.8% fewer lines of code than Next.js to make the exact same app. Less code means less to review, less to debug, less energy, and less cost. AI-assisted coding, (with other app builders like Next.js), generates too much code, making changes unpredictable and nearly impossible to review.

PackageJS used 80% fewer tokens than Next.js

Building a simple to-do app with PackageJS and Claude Code used only 40,000 tokens, and worked on the FIRST try, compared to the same app generated in Next.js, which used over 200,000 and threw multiple errors that needed to be debugged.
